A two-stage-to-orbit (TSTO) spaceplane concept developed in 1993 is
revisited, and new information is provided to assist in the
development of the next-generation space transportation vehicles.
The design philosophy, TSTO spaceplane concept, and the design
method are briefly described. A trade study between cold and hot
structures leads to the choice of cold structures with external
thermal protection systems. The optimal Mach number for staging the
second stage of the TSTO spaceplane (with air-breathing propulsion
on the first stage) is 10, based on life-cycle cost analysis. The
performance and specification of a prototype/experimental (P/X)
TSTO spaceplane with a turbo/ram/scramjet propulsion system and
built-in growth potential are presented and discussed. The internal
rate of return on investment is the highest for the proposed TSTO
spaceplane, vis-A-vis a single-stage-to-orbit (SSTO) rocket vehicle
and a TSTO spaceplane without built-in growth. Additional growth
potentials for the proposed spaceplane are suggested. This
spaceplane can substantially decrease access-to-space cost and
risk, and increase safety and reliability in the near term It can
be a serious candidate for the next-generation space transportation
system.
