There are different phases of ejection, with potential for injury to the pilot. Sequentially, these phases are – (a) Canopy separation/ fragmentation; (b) Egress; (c) Ram Air/ Wind blast; (d) Wind drag deceleration; (e) Free fall; (f) Parachute deployment, and (g) Landing. As per the phase of ejection, a pilot can sustain various injuries with spinal injury being the commonest.
The force moving an ejection seat must be sufficient to enable it to clear the tail of the disabled aircraft. To achieve this, the seat must accelerate from zero velocity to about 12.2 to 24.4 m/sec (40 to 80 ft/sec). This gives a rapid rate of rise of acceleration or jolt factor, which must remain …
An ejection seat is a rigidly constructed metallic seat, which is forcibly ejected from the aircraft cockpit by means of an explosive charge.
Escape from a crippled aircraft, be it a commercial aircraft, full of passengers, or a combat aircraft with one or two aircrew, ensuring a safe exit is the first and the paramount step towards survival. Unlike the combat aircraft with its ejection seats, transport aircraft, helicopter and most of the training aircraft, except jets, do …
Motion Sickness, characterised by nausea, pallor, cold sweating and vomiting, occurs when humans are exposed to unfamiliar motion stimuli, either real or apparent. The earliest known reference to motion sickness was ‘sea-sickness’ but now this term encompasses symptoms induced by any form of motion or even in the absence of physical motion it is known …
