A method for aiding a helicopter pilot to avoid a heat seeking missile includes the step of detecting a threat from a missile. The method also includes the step of reducing heat emanating from the helicopter's engine and rapidly reducing altitude. Then, when the threat has passed flight is resumed.

A method for aiding a helicopter pilot to avoid a heat seeking missile includes the step of detecting a threat from a missile. The method also includes the step of reducing heat emanating from the helicopter's engine and rapidly reducing altitude. Then, when the threat has passed flight is resumed. A system for accomplishing the above is also described which simultaneously reduces engine temperature, deflects the exhaust gases, injects water into the exhaust gases, reduces altitude and launches a countermeasure.

What is claimed is: 1. A method for aiding a pilot to avoid being struck by a heat seeking missile, said method comprising the steps of: detecting a threat of a heat seeking missile; providing a computer for automatically reducing the heat emanating from a helicopter engine upon detection of the threat by a heat seeking missile; automatically rapidly reducing altitude; and automatically resuming flight when the missile threat has passed. 2. A method for aiding a pilot to avoid being struck by a heat seeking missile according to claim 1, in which the heat emanating from the engine is reduced by reducing power. 3. A method for aiding a helicopter pilot to avoid being struck by a heat seeking missile according to claim 2, which includes the step of deflecting hot exhaust gases. 4. A method for aiding a pilot to avoid being struck by a heat seeking missile according to claim 2, which includes the step of dissociating the hot exhaust gases. 5. A method for aiding a pilot to avoid being struck by a heat seeking missile according to claim 2, which includes the step of injecting water into the hot exhaust gases. 6. A method for aiding a pilot to avoid being struck by a heat seeking missile according to claim 3, which includes the step of injecting water into the hot exhaust gases. 7. A method for aiding a pilot to avoid being struck by a heat seeking missile according to claim 4, which includes the step of injecting water into the hot exhaust gases. 8. A method for aiding a pilot to avoid being struck by a heat seeking missile according to claim 3, in which the hot exhaust gases are deflected upwardly. 9. A method for aiding a pilot to avoid being struck by a heat seeking missile according to claim 1, in which the altitude of the aircraft is reduced by auto rotation. 10. A method for aiding a pilot to avoid being struck by a heat seeking missile according to claim 2, which includes the steps of deflecting the hot exhaust gases, injecting water into the hot gases in which the steps of reducing the heat emanating from the engine, deflecting the hot exhaust gases and injecting water into the hot gases are done simultaneously. 11. A method for aiding a pilot to avoid being struck by a heat seeking missile according to claim 10, which includes the steps of establishing a safe zone based on the speed, altitude and weight of the aircraft, monitoring a safe zone and preventing a rapid reduction in altitude when the aircraft is outside of the safe zone. 12. A missile defense system in a helicopter for avoiding a strike by a heat seeking missle, said system comprising: means for detecting a threat by a heat seeking missile; means for reducing the heat emanating from a helicopter's engine upon detection of a threat by a heat seeking missile including a computer for automatically reducing the speed of the engine upon detection of a threat by a missle; means for deflecting hot exhaust gasses upwardly toward a helicopter's rotor; means for injecting a mass of water into the hot exhaust gasses; means for rapidly reducing the altitude of the aircraft by auto rotation; means for simultaneously activating said means for reducing the heat emminating from a helicopter's engine upon detection of a threat by a heat seeking missile, said means for rapidly reducing the altitude of the helicopter, said means for deflecting the hot exhaust gasses upwardly and said means for injecting a mass of water into the hot exhaust gasses; and, means for establishing a safe zone based on the altitude, speed and weight of the helicopter and for deactivating the means for rapidly reducing altitude when the helicopter is outside of the safe zone. 13. A method for aiding a helicopter pilot to avoid being struck by a heat seeking missile, said method comprising the steps of: establishing and monitoring a safe zone based on altitude, airspeed and gross weight of a helicopter; detecting a threat by a heat seeking missile; providing a computer for automatically reducing the heat emanating from the helicopter engine; automatically rapidly reducing the altitude of the helicopter within the safe zone; and automatically resuming flight when the missile threat has passed.
