This paper discusses the equations of motion which govern the aerodynamic performance of USAF fighter aircraft immediately after ski-jump takeoffs. By a careful selection of coordinate systems and independent and dependent variables, we eliminate the need for repetitive time-history integration of the nonlinear, coupled equations. This allows a relatively simple, but exact solution of the problem. Detailed results are presented for the F-4, A-10, F-15 and F-16 for two cases -- a nominal baseline for constant pitch attitude, and a 'best possible' case which produces the lowest achievable takeoff speeds.
