MMB281 T1.051 1 Question 1. Using TRIZ tools solve the following problem: To rescue jet fighter pilots in the case of emergency ejection seats have been developed. A charge of gun powder propels the seat out of the aeroplane and then parachute is opened. Modern ejection seats are designed as “zero – zero” seats. In other words they could be used at zero speed and zero altitude when aeroplane is stationary on the ground. When the seat is ejected at a speed the pilot suffers an impact from the air flow. The impact pressure is proportional to velocity squared at a medium speed and to velocity cubed at high speed. The speed of modern fighters approaches 3000km/h. If a conventional seat is ejected at such a high speed the pilot will be certainly killed. Designers of F-111, long range strike aircraft (USA) introduced a concept of ejecting the whole pilots’ compartment with two crew members, which rescues the crew in the case of emergency ejection at supersonic speed. The drawback of this system is high cost and complexity. The Russian design group “Zvezda” (Designer General G. Severin) developed the first ejection seat that could be ejected at
