A flight simulation program that could simulate the flight of an spaceplane from the ground surface to the orbit around the earth was developed. This program is the advanced version of the general purpose program for the flight simulation which has been developed in the National Aerospace Laboratory of Japan. Two programs are available to analyze the rigid body motion with six degrees of freedom or the mass point motion with three degrees of freedom. They are written in FORTRAN. The merits and limitations of the program are as follows: (1) it is composed of two package programs, that is, fuselage models and onboard calculations (these packages are replaceable and thus the program is widely usable); (2) the heating rates of the fuselage, load factors and dynamic pressures are calculated along the flight path and are used for the assessment of the path; (3) the earth is assumed to be a sphere and the revolution is neglected (the angular velocity of the rotation is assumed to be constant); (4) a U.S. 62 standard atmosphere table is used; (5) it contains the models of the westerly wind, the steady wind in the low altitude, the gusts and the wind shears. The contents of the program and the construction of the mathematical model are described and the good results of the evaluation are presented in which the three degrees of freedom flight simulation program was tested using the data of the space shuttle of U.S.A.
