Performance Evaluation of a High-altitude Launch Technique to Orbit Using Atmospheric Properties

The purpose of this paper is to perform the feasibility and performance evaluation of a High-altitude launch technique using high altitude atmospheric properties to near earth orbits. It is suggested in thispaper to analyze a different type of launch from a high altitude to the LEO orbit. Two altitudes serve asan initial launch conditions, 20 to 40 km that is evaluated according to the thrust profile variations with respect to the vehicle’s payload and under different orbital altitude. the trajectory equations used in the simulation code also take into consideration Spectral and Diffusive reflection model for near spaceconditions. The methodology is based on the previously mentioned model that calculates the forcesaffecting a flat plate as it gains altitude. To continue, for validation to problem results, are simulated the mission of SAFIR-2 launch vehicle for it and the output data are compared with the operational phase
