CASE STUDY A pilot was taxiing his air-force jet when theejector seat fired, sending him upwards to then crash down onto theairfield, where he died from the impact injuries. Ejector seats aredesigned to enable a pilot to escape from a disabled aeroplane.When activated by the pilot (that is the normal way they work) arocket pushes the seat and pilot out of the aircraft and at the topof the trajectory a parachute deploys to bring the pilot to theground safely. This seat was not designed to enable a safe ejectionat ground level, as the parachute would not have time to deploybefore the seat hits the ground. Use the search term â€œRAF EjectorSeatâ€ to discover a host of web sources for information on thistragic case i. Define the appropriate Event and draw, with thebrief written explanation, a Mechanism analysis logic diagram. [25marks] ii. Determine and explain your choice of the â€˜questionsâ€™which you would use to provide structure to the Outcome process anddraw an Outcome Analysis diagram for the case based on thosequestions.

The purpose of an ejection seat is pilot survival The pilot typically experiences an acceleration of about 1214g Western seats usually impose lighter loads on the pilots 1960s70s era Soviet technology often goes up to 2022 g with SM1 and KM1 gunbarreltype ejection seats Compression fractures of vertebrae are a recurrent side effect of ejection It was theorised early on that ejection at supersonic speeds would be unsurvivable extensive tests including Project Whoosh with chimpanzee test subjects were See Answer
