Ehhh, con toda la mezcla rara que piensa administrar el Ecuador entre F-1, Mirage 50, Chetaah, Kfir... para que más 6 Sukhois... por Dios, es más que suficiente contra Colombia, y algo asi contra Peru.
Además, Ecuador es un pais pequeño, mucho más que sus vecinos Colombia y Peru, y ambos siempre se han conformado con menos que Ecuador.
En vez de pensar en tanto avión de alto rendimiento, podrian pensar en meterle más dinero a su ala de transporte que no pasa un buen momento, mejorar el asunto de los helicopteros para que por economizar no les pase de nuevo lo de los Dhruv, concentrarse más en COIN para controlar la forntera norte de la que tanto se preocupan.
Sale más barato y eficiente patrullar Esmeraldas y Sucumbios con SuperTucanos que con aviones de alto rendimiento.

Si son culpables en fin, pero si no lo son ya mellaron su honorabilidad y profecionalismo como pilotos, oficiales y hombres.
Algo que tambien se ha sufrido a veces en los ultimos tiempos en el Peru. y por eso lo digo.

Dhruv fiasco - CAG report tabled
THE DHRUV advanced light helicopter (ALH) was indigenously designed for the Army and the Air Force to operate in mountainous areas like Siachen, where heights range from 10,000 to 20,000ft. However, the annual report of the Comptroller and Auditor General of India (CAG) states that the Army inducted 40 ALHs - at a cost of about Rs1,747 crores - which, due to technical shortcomings, cannot fly above 5,000m (eqiuvalent to 15,000ft).
In the report tabled in parliament, the CAG said the helicopters manufactured by public sector aviation giant Hindustan Aeronautics Limited (HAL), were in the process of induction with ‘technological gaps’. The CAG cautioned that it could impact the operational preparedness of the Army. Elaborating upon this point, the report said the Army, in its qualitative requirement projected in 1995, wanted a light helicopter which could fly at a height of more than 6,500m. The first four ALHs produced in 2001 failed to meet this requirement due to the limitation of the B2 engine used in the helicopter adding that the vibration levels of the helicopter were not within acceptable limits.
Despite the shortcomings, four ALHs were accepted by the Army and an order was placed for eight more in order to sustain the production lines of HAL. A waiver (that put aside the need for meeting with qualitative requirements) was granted by the then Defence Minister on November 2001 as a one-time exception based on the assurances of HAL. The aviation company said it would identify a more powerful engine to replace the B2 engine and reduce the basic empty weight of the helicopter from 2,550kg to 2,450kg. CAG noted that as of December 2008, HAL failed to overcome these shortcomings even after five years even though it had tied up with a foreign company to develop a more powerful engine.
It said that the inability of the ALH to fly above 5,000m was due to the inability of HAL to reduce the basic empty weight of the helicopter. “Thus due to the delay and inability of HAL to develop the ALH according to the Army’s requirement, the Army is saddled with 40 ALHs with technical shortcomings,” it observed. The CAG also said the Army was compelled to rely on the old fleet of single-engine Cheetah and Chetak helicopters which use a technology that is over 30 years old.
Moreover, the Army signed a contract in 2007 for 105 ALHs (fitted with Shakti engines) worth over Rs9,490 crores. Delivery was to commence from 2008-2009 onwards provided the engine was evaluated by August 2008.The Army stated in September last year that the engine was power-deficient and that necessary improvements were underway. “The failure of the Army to acquire suitable ALHs timely, has led to considerable delay in de-induction of the Cheetah and Chetak helicopters, which may impact operational preparedness especially in high-altitude areas,” the report said.

*An unofficial first flight took place on 20 August 1992.
Design Features: The Dhruv features a 'System Bolkow' four-blade hingeless main rotor with carbon fibre composite blades. The blades have advanced aero foils, swept back tips for reduced nose, and feature a ballistic tolerance against bullet hits of up to 12.7mm calibre. The fibre elastoner rotor head holds the blade between a pair of CFRP star-plates, with manual blade folding and a rotor brake provided as standard equipment. A four blade bearing-less crossbeam tail rotor is fitted on the starboard side of the pylon. Vibration damping is provided by an anti-resonance isolation system compromising four isolator elements between the fuselage and the main gearbox. An integrated drive system transmission comprises of the rotor hub, main transmission, upper controls and main rotor hydraulics. The Dhruv also features a four axis automatic flight control system, with an integrated control & stability augmentation system from France.
The airframe makes extensive use of composites (Glass Fibre, Carbon and Kevlar) and accounts for 29% of overall structural weight and 60% of surface area. The military variants include crashworthy fuel tanks, frangible couplings and infra-red suppressors for the engines. The helicopter design enables the crew to survive vertical impacts of up to 30 feet per second, due to the safety seats and a design of controlled deformation of fuselage crumple zones. The cabin was designed to seat 12 people, however 14 can be accommodated in a high-density configuration. Rearward-sliding passenger doors are featured on either end, with large clamshell doors at the rear of the cabin. The clamshell doors can be removed, in exceptional cases, to carry unusual & unwieldy loads. An underslung load hook is standard on military variants. The air ambulance variant enables the Dhruv to accommodate two to four stretchers, with a couple of attendants.
Avionics: A communication radio (U/UHF, HF/SSB and standby UHF modes), IFF & intercom, with a Doppler navigation system, TAS system, radio altimeter and ADF are standard in all military variants. A weather radar and the Omega navigation system is optional on the naval variant.
Engine: The Dhruv was originally powered by a pair of TM333-2B turbo shafts developing 746 kW (1000 shp) from Turbomeca of France. This was later switched to the LHTEC CTS800-4N turbo shaft (from the then Allied Signal of USA - now Honeywell) developing 970 kW (1300 shp). The more powerful CTS800-54 turbo shaft developing 1235 kW (1656 hp) was offered as an option. However these engines were embargoed by the US, for imposing sanctions on India for her nuclear tests in May 1998. Connections were re-established with Turbomeca and the TM333-2B2 engine was selected, developing 825 kW (1100 shp) at take-off, with growth potential to 900 kW (1200 shp) for subsequent versions and features full authority digital electronic control (FADEC). AIN Online reported in February 2004 that Turbomeca will supply 318 TM333-2B2 engines to HAL for the series production. The aviation journal also stated that Turbomeca has agreed to increase the offsets associated with this deal by transferring more work to HAL, which will now produce the engine's turbocharger and other accessories, including the fuel systems. HAL will also be securing repair licenses for the engines.
The Indian Army tested the Dhruv in the 1999 Kargil war against Pakistan. While the advantages in hot-and-high performance parameters and altitude limitations were obvious when compared to the HAL Cheetah, the Army wanted more out of the TM333-2B2 engine. Thus a Memorandum of Understanding (MoU) was signed on 12 September 2000 between HAL and Turbomeca to develop a turbo shaft more powerful than the TM333-2B2 engine. Called Shakti in India and Ardiden 1H in France, the engine is expected to develop 900 kW (1200 shp). The engine is set to complete its first test bed run only in mid-2005. Around 300 to 350 Shakti/Ardiden-1H engines, worth $400 to $500 million in total, are expected to be produced at Bangalore under the deal. The first engines will not be ready before 2006 and will replace the existing TM33-2B2 engines on the production line. The engine will eventually be the standard power plant on the Dhruv and earlier production examples that entered service with the TM333-2B2 engine, will be retrofitted with the new engine. HAL has a 11% stake in the overall program and Indian engineers are based at Turbomeca's headquarters at Bordes in the southwest of France to assist with the development.
Comments: From July 1984, work at HAL was supported by MBB of Germany (now Eurocopter Deutschland) to develop a helicopter for military and civilian uses in India. On 18 March 2002, the Coast Guard became the first military service to induct the HAL Dhruv (CG-851) at a ceremony in Bangalore and three examples are currently in service. The Army received its first three examples (IA-1101, IA-1102 and IA-1103) on 20 March 2002 and the Navy received its first pair (IN-701 and IN-702) on 28 March 2002. The Air Force received its first pair (J-4041 and J-4042) on 30 March 2002. The Dhruv production for the military is expected to be 120 for the Army, 120 for the Navy, 60 for the Air Force and seven for the Coast Guard over a period of of 15 years. To meet this target, HAL is expected to progressively increase production every year, going from 12 to 16 aircraft, then to 20 and finally reaching a production peak of 24 aircraft. Some sources indicate that the peak production rate could be as high as 36 aircraft per year.
The 21st production aircraft delivered to the Army, will be the first with a glass cockpit and weapons systems integrated. The Army's WSI helicopters will feature a chin-mounted, three barrel 20mm gun from Lockheed Martin and four pylons - each having two hard points - which will enable it to carry eight Nag anti-tank guided missiles, four 68mm or 70mm rocket pods or four tube-launched air-to-air missiles.

estos aviones estaran en servicio al menos unos 10 años y que "compartiran" el rol de caza supersonico con el nuevo avion que se adquiera de aqui a 5 años aproximadamente ( todo indica que sera el su-30)

Esta nave tiene 800 horas de vuelo desde que está aquí. Ha volado de Guayaquil a Quito y viceversa y lo ha hecho entre 17 y 20 mil pies de altura

Entonces van a pasar dos cosas:
O vuelan solo los SU-30, nada mas (por que no hay plata)
O la FAE va a poner una exhibicion con estos en los hangares y cobrar por la entrada
SU-30´s?, cuantos? 2? digo, para que vuelen al unisono sin que tiren al piso el presupuesto..es un aparato CARISIMO de mantener y operar, lujo que solo Venezuela se puede dar por estos lares, a menos que nos subsidien el uso y manejo de estos aparatos.Ya el hecho de que el presidente ande por Rusia nos hace clientes del Su-30?en lo personal, me pareceria fantastico que operaramos este tipo de aeronaves, sin importar que sean de la Madre Patria (de los de ahora).
Mejor compremos esos Su-27 que USA esta vendiendo a 5 Millones cada uno, son 2, pero el contrato de mantenimiento, por ambos, es de 30 millones por 5 años..saca numeros...

TM 333
The TM 333 powers the Dhruv, a twin-engine civil and military helicopter built by Hindustan Aeronautics Ltd. over 250 TM 333 have been delivered, logging more than 55,000 hours in flight.
Designed for 5 to 6-ton-class helicopters, the TM 333 was originally intended to power Eurocopter's twin-engine Dauphin and Panther helicopters. Developed on the Panther, the TM 333 found its first commercial application on the Dhruv, the helicopter built by HAL (Hindustan Aeronautics Ltd) of India.
The TM 333 2B2 develops 825 kW (1100 shp) at takeoff, with growth potential to 900 kW (1,200 shp) for subsequent versions.
The TM 333 2B2 is the sole production engine used on the Dhruv. Several hundreds engines have been ordered, with deliveries in progress. The Dhruv has been ordered by the Equador.
The TM 333 2M2, new variant of the TM 333 2B2, will power the Cheetal, the upgraded version of the Cheetah (Lama), and the Chetan, the upgraded version of the Chetak (Alouette III).
The first flight of the Cheetal passed off on February 1 2003, and the flight of the Chetan passed off on February 1 2005.

The helicopter, which is built to FAR 29 specifications, entered series production in 2000. 18 Dhruv helicopters were delivered to Indian Defence Forces in 2000-2003, eight to the army, three to the navy, four to the air force and three to the coast guard. The army received its first three Dhruvs in March 2002. By June 2008, 76 helicopters had been delivered to the Indian army and air force with 159 more on order. The Indian Navy has decided not to place any further orders.
The fleet of the Indian Air Force Display Team, Sarang (Peacock in English) includes the Dhruv helicopters.
"Dhruv is a multi-role and multi-mission helicopter for army, air force, navy, coast guard and civil operations."In June 2008, HAL received the first export order for the Dhruv - seven helicopters for the air force of Ecuador.
In August 2006, Indian Air Force and Coast Guard Dhruv helicopters were instrumental in rescue operations after devastating floods in India
Over 500 people were rescued.
In February 2007, the Dhruv was qualified for high-altitude / low-temperature operations in Kashmir and Jammu.
In August 2007, maiden flights took place of the Dhruv powered by the new Shakti engine and of the weaponised variant of the helicopter. And In September 2007, the Indian Army announced that the Dhruv was ready for deployment to the Siachen sector in the Himalayas. The helicopter was deployed to the high-altitude airbase at Manasbal (Srinagar) and, in October 2007, a Dhruv helicopter flew at a record altitude of 27,500ft in Siachen. The armed variant is scheduled for initial operating capability in December 2009.

Accidente de helicóptero
FAE revisa el contrato para verificar si hubo falencias
El general Rodrigo Bohórquez defendió el proceso de compra de las siete aeronaves. Manifestó que no fue una adjudicación realizada a dedo
Redacción Quito
La propia Hindustan Aeronautics Limited (HAL), que vendió los siete helicópteros Dhruv a la Fuerza Aérea Ecuatoriana (FAE), dará seguimiento a las investigaciones del siniestro ocurrido durante el aniversario 89 de la Aviación.
Para ello, una comisión de tres técnicos llegará a Quito mañana o sábado, según confirmó Juan Cortez, de la empresa Sumil, representante de HAL en el país.
El funcionario garantizó que la próxima semana se conocerá de primera mano la documentación del contrato suscrito con la FAE.
Al respecto, EXPRESO reveló que se determinaron tres tipos de problemas en cuanto al cumplimiento de las especificaciones: palas de rotación principal y motores de fabricación anterior al 2008, seis de diez motores tienen quince años de vida menor a lo convenido. Por último, no cuentan con el sistema mejorado de alerta de proximidad en tierra.
El comandante de la FAE, general Rodrigo Bohórquez, defendió el proceso de adquisición al asegurar que pasó por cinco comisiones técnicas de las Fuerzas Armadas con diferentes integrantes, y que al final se decidieron por la oferta de los Dhruv, que asciende a 45,2 millones de dólares.
“Quiero que quede claro que no fue una adjudicación a dedo. Hubo un concurso de licitación entre cuatro empresas y luego los técnicos de la FAE hicieron un informe, donde se establecía que esos helicópteros indios eran los mejores”.
Entre las firmas que participaron están Elbit (Israel), Eurocopter (España), Kazan (Rusia) y HAL, de la India.
Respecto a las especificaciones cuestionadas, el alto oficial reconoció que se está revisando todo el proceso.
“Si no hay la aceptación de la comisión que recepta los helicópteros, tendremos que exigirles que nos devuelvan el motor del 2008 y con los otros componentes entendería que vamos a hacer lo mismo. Estamos en el proceso, revisando todo nuevamente, y si hubiesen partes que no están de acuerdo al contrato es nuestra responsabilidad exigirles que cumplan las normas del mismo”, dijo.
En el caso de los motores fabricados por Turbomeca, antes del 2008, que aduce es un motor virgen, Bohórquez indicó “queda de nuestro lado aceptarlo o no, y en eso estamos para que se cumpla en el contrato”.
Cortez aclaró que el sistema de aproximación a tierra está funcionando y reiteró que se entregarán los documentos de los equipos que están montados en los helicópteros. (LCF)
La tercera nave advirtió sobre la emergencia
El capitán Carlos Enríquez certificó que en el 2008 viajaron a la India cuatro oficiales y 13 aerotécnicos de la FAE, para realizar el curso en los helicópteros Dhruv, respecto de los que destacó la operatividad, facilidad y modernidad, en relación a otras naves que antes había pilotado.
A inicios del presentó año se desplazaron diez pilotos más para un curso teórico en las instalaciones de la empresa HAL. “Los helicópteros están acorde a las necesidades y requerimientos que tiene la Fuerza, hasta ahora no se ha presentado ninguna novedad”, dijo.
El día del accidente, el oficial dirigía las operaciones de los tres Dhruv. Al respecto reiteró que la maniobra que hizo la segunda nave era una “pasada simple con un viraje”, pero la emergencia la conoció por el tercer helicóptero que advirtió que sus compañeros tenían problemas. (LCF)
Militar venezolano afirma que donación de aviones a Ecuador incluye misiles
Publicado el 29/Octubre/2009 | 15:07
La donación de seis aviones Mirage de Venezuela a Ecuador incluye misiles para esas aeronaves, reveló hoy el segundo comandante de la Aviación Militar Venezolana, general José Gregorio Pérez, durante la entrega de los tres primeros aparatos.
"Con los misiles que también le vamos a entregar a Ecuador (los aviones) tendrán mayor capacidad de defensa", dijo el oficial a periodistas en una base de la localidad ecuatoriana de Taura, 280 km al suroeste de Quito.
Pérez, que no precisó el número de proyectiles, señaló que los Mirage 50 son de "alto performance", desarrollan una velocidad que duplica la del sonido y tienen "gran capacidad de ataque".
"Es un orgullo que vayan a seguir cumpliendo labores de seguridad y defensa en" Ecuador, "un país más que hermano", añadió en un discurso.
El oficial destacó que los presidentes de Venezuela, Hugo Chávez, y de Ecuador, Rafael Correa, han creado "una relación que nos permite hacer este tipo de intercambios" y proclamó la consigna "patria, socialismo o muerte".
Los tres primeros aviones llegaron hoy tripulados por pilotos venezolanos, tres días después de lo previsto debido a una polémica sobre un permiso de Colombia para que cruzaran su territorio.
El jefe del Comando de Operaciones Aéreas y Defensa de Ecuador, general Alonso Espinosa, indicó que la donación venezolana "cubre una debilidad grande que tenía Ecuador en cuanto a capacidad de ataque aire-mar".
"Es decir, para poder responder en caso de que haya una flota enemiga que se esté aproximando a bloquear nuestras líneas de comunicación marítima", explicó. (AFP)
