**URGENT need help in pilot eject system**

i am an undergraduate from a university. we are now working on an assignment on design a system of jet eject seat. and we need to use the numerical method and MATLAB program to simulate the result. well, hope you all might help us, suggest us, help us in solving this problem..

"""

an British Aerospace jet - Hawk (MK 108 & 208), need an eject seat system.

the eject seat need to fulfill the following spec.

the jet flying angel = +/- 30 degree

the maximum high of the ejected seat = 0.03 - 0.125km

the distance of the ejected seat landing from the jet = 0.10 - 0.25km

speed of the jet = mach 1.1

seat mechanism + max load = 110kg

the maximum acceleration to eject the seat = 22g

we need to find out a system to safely eject the pilot from the plane
