Galix al parecer tienes razon, USA ya esta trabajando en un nuevo motor para el AMRAAM. Esta informacion fue tomada en el forum del F-16 net.
ATK Awarded Rocket Motor Technologies Development Contract for Next Generation Air-to-Air Missiles
(Source: ATK Alliant Techsystems; issued October 29, 2009)
MINNEAPOLIS --- Alliant Techsystems has been awarded a research and development contract for the Counter Air / Future Naval Capabilities (CA/FNC) program to develop technologies that can be incorporated into next generation air-to-air missile systems.
The nearly $10-million contract was issued by the Naval Air Warfare Center Weapons Division, China Lake, California. ATK will work in concert with NAWCWD to identify specific propulsion technologies to develop for integration into future missile systems. The work is expected to be completed by June 2013.
The scope of the CA/FNC program is to develop technologies that will extend missile range, decrease time-to-target, improve end-game maneuverability, and improve the rocket motor's response to insensitive munitions (IM) stimuli. These improvements are oriented towards the 7-inch diameter Advanced Medium Range Air-to-Air Missile (AMRAAM) that is currently in use by the U.S. Navy, U.S. Air Force, and many allied nations, but will be applicable to other air-to-air missile systems.
There are four main areas that ATK will be concentrating their development efforts on which include: high burn rate propellants for improved kinematics; improving case stiffness for reduced weight and agility; low erosion nozzles for improved performance; and multi-pulse propulsion for end-game maneuverability. Additionally, ATK will address the IM requirement by incorporating affordable solutions including an advanced propellant formulation, a low cost composite case, and mitigation safety devices proven on other tactical rocket motor programs.
"By drawing on our heritage rocket motor experience, proven service life of fielded propulsion systems, and incorporating unique technologies, ATK will develop a robust, affordable propulsion system to meet current and future counter air targets with the potential to influence all future air-launched missiles. ATK's proven leadership in the development of advanced propellants, IM solutions, and pulse motors will pay benefits in developing this improved propulsion system for the U.S. Navy," said Bart Olson, Vice President and General Manager of ATK's Tactical Propulsion and Controls Division.
ATK is the sole source rocket motor supplier for all currently fielded U.S. air-to-air missile systems that include the AMRAAM and AIM-9X. The technologies developed under this contract will ensure ATK maintains its leadership role in providing rocket motors for next generation air-to-air missiles.
ATK is a premier aerospace and defense company with more than 18,000 employees in 22 states, Puerto Rico and internationally, and revenues of approximately $4.8 billion.
Ademas quiero compartir esta otra informacion sacada del mismo lugar en la cual comparan el Meteor. AMRAAM y el R77..es interesante
The subject was extensively discussed in another forum, so I am able to draw on some of that material, plus briefings I have had from MBDA, Raytheon, and Vympel.
The MBDA Meteor was evaluated in the late 1990s against two proposals by Raytheon – the AIM-120C-8 ERAAM and the ramjet-powered FMRAAM. All had been proposed as candidates to meet the United Kingdom's Staff Requirement (Air) SR(A)1239.
At the time, Raytheon saw the FMRAAM as a relatively risky development programme given the proposed timescale, so offered to field the ERAAM on a shorter timescale as an interim weapon that did not fully meet the RAF’s requirement.
ERAAM would have combined the AIM-120C-7 guidance and warhead sections with a new dual-pulse solid-propellant rocket motor.
However, the AIM-120D did not opt for this route, but uses the existing single-pulse rocket motor from the –120C-7 version. It gains its additional kinematic and weapon effectiveness performance from a GPS-aided navigation system plus new guidance software.
So assuming that the AIM-120C-8 ERAAM and AIM-120D are in the same performance class, a level that did not meet the UK requirement, we must assume that this class of performance was below that offered by Meteor.
But Raytheon won't be standing still - work is under way to improve the -120D.
This says nothing about their relative maximum range; long range was never a direct requirement for Meteor. The prime requirement for the latter missile was the high kinematic performance needed to provide a 'no escape zone' more than three times that of the (then-current?) models of AMRAAM. Although this level of kinematic performance results in a missile with a maximum range of more than 100 km, its main purpose is to ‘run down’ a target 80 km distant, even if that target turns away from the air battle and attempts a supersonic dash in the hope of outrunning the threat missile.
The Russians are not always consistent in how they use the designation R-77M. It is often used to indicate the proposed ramjet-powered version of the R-77 (often referred to as R-77M-PD or RVV-AE-PD). This is probably no longer an active programme. Several years ago, Vympel chief designer Gennady Sokolovsky told me that the design was only an experimental project and stressed that it was not a planned operational weapon.
There is a new Izdeliye 180 upgrade of the R-77 expected to enter service around 2014, but according to Russian sources it is only intended to match the performance of the AIM-120C-7. The earlier Izdeliye 170-1 upgrade (which probably corresponds to the RVV-SD export missile revealed last year) is of lower performance than Izdeliye 180.
In the long run, Russia will produce air-to-air missiles in the performance class of the AIM-120D and beyond. But my understanding is that these will use some form of high-performance rocket motor.
