Reusable thrust-powered sled mounted on an inclined track for launching spacecraft and airborne vehicles at supersonic speeds

Abstract

This invention will allow a reusable thrust-powered sled mounted on an inclined track to launch spacecraft or airborne vehicles from earth at supersonic speeds using existing technology properly integrated into an inclined track system. If launched up a tunnel track, a rear blast shield can trap the rocket exhaust to provide a pneumatic boost upon launch. The sled can also launch ramjet or scramjet powered vehicles from earth by achieving the Mach 2+ speed necessary to ignite their engines. This system is much safer than the traditional method of launching rockets since weather is less a factor and the launch can be aborted if problems develop. Moreover, it is far less costly since the engines on the sled can be reused hours after a launch and the track can accommodate a variety of sleds to launch objects of many different sizes.
