![]() ![]() roughly a 39.4% fuel fraction (sounds about right). if 85% of the motor's mass is the fuel, we have about 132 lbs of fuel in the AMRAAM-A ![]() Motor weight = 156 lbs (WPU-6/B HTPB rocket motor weight as per Raytheon)Īpproximate specific impulse = 245 seconds (typical of HTPB solid motors)Īpproximate fuel fraction of motor = 85% (typical of robust aluminum cased aerospace rocket motors) Launch weight = 335 lbs (Published stats) In otherwords, it assumes an all-boost motor not a boost sustain motor.įor example, let'a take a look at the AIM-120A AMRAAM which we have some decent info on. None is used to provide just enough thrust to sustain a given velocity. This assumes that all the fuel is used to get the missile as fast as possible and It goes like this:-Ĭhange in Velocity (Delta V) = 10 x Specific Impulse x LN (initial weight / final weight) m/s I want to take this opportunity to introduce everyone to a very simple formula thatĬan be used for estimating the performance of a missile. Some of which are well backed by facts, some are so far out there it is like claiming that There has been a lot of arguments over the performance of A2A missiles here. 15th February 2010 at 14:58 - Edited 1st January 1970 at 01:00Ĭola had a good briefing how it works, here. then we have optimal conditions, and this is what PR guys quote when they sell their missiles.Ī missile has ~7 sec worth of fuel to burn If on the other hand the launching aircraft was closing in at M1.5 at missile launch, and the target was also closing in at supersonic, while also having a lower altitude then launch a/c, and flying a straight line so that the missile does not have to waste energy on anything, then there is no hope of the missile ever gets close to the target. Speed of launching aircraft at missile launch in the direction towards the target is also a very important parameter, lets say it was flying away from the target at launch, and the target was also flying away, Then we have sea level, pretty good maneuverbility but only WVR. Next comes high altitude in atmosphere, still long range but real poor maneuverbility. In space, the range of an AMRAAM is 500 light-year, but the probability of a hit is zero, cause the fins has no authority to change the missiles direction. This notice of a potential sale is required by law and does not mean the sale has been concluded.- 15th February 2010 at 11:58 - Edited 1st January 1970 at 01:00 defense readiness as a result of this proposed sale. Government or contractor representatives to the Netherlands. Implementation of this proposed sale will not require the assignment of any additional U.S. There are no known offset agreements proposed in connection with this potential sale. The principal contractor will be Raytheon Missiles & Defense, Tucson, AZ. The proposed sale of this equipment and support will not alter the basic military balance in the region. The Netherlands, which already maintains AMRAAM missiles, will have no difficulty absorbing this equipment and support into its armed forces. The proposed sale will improve the Netherlands’ capability to meet current and future threats by deterring regional threats, strengthen its homeland defense, and enable interoperability and standardization between the armed forces of the Netherlands and the United States. This proposed sale will support the foreign policy and national security of the United States by helping to improve security of a NATO ally which is an important force for political stability and economic progress in Northern Europe. The total estimated program cost is $39 million. Government and contractor engineering, logistics, and technical support services, and other related elements of logistics and program support. Also included are containers, weapon systems support and support equipment, spare and repair parts, publications and technical documentation, U.S. The Government of the Netherlands has requested to buy sixteen (16) AIM-120C-8 Advanced Medium Range Air-to-Air Missiles (AMRAAM). The Defense Security Cooperation Agency delivered the required certification notifying Congress of this possible sale today. WASHINGTON, JThe State Department has made a determination approving a possible Foreign Military Sale to the Government of the Netherlands of sixteen (16) AIM-120C-8 Advanced Medium Range Air-to-Air Missiles (AMRAAM) and related equipment for an estimated cost of $39 million. The Netherlands – AIM-120C-8 Advanced Medium Range Air-to-Air Missile (AMRAAM)
