The history of the VTOL SSTO (single stage to orbit) concept and the Phoenix designs is reviewed. The role the Phoenix concept played in stimulating consideration of the SSTO approach by the U.S. Government in ongoing SSTO concept studies is also discussed. It is pointed out that these studies are currently expected to lead to prototype hardware development aimed at demonstrating the SSTO

Four engines were built and were used on the DC-X and the upgraded DC-XA VTOVL SSTO launch vehicle demonstrators. The DC-Y was a conceptual vehicle design and did not use these engines. The RL-10A-5KA was proposed for use on the Kistler K-1 vehicle but was not selected. Aug 19, 2013 Feb 24, 2021 prototype hardware development aimed at demonstrating the SSTO approach by 1995-97 in the form of the McDonnell-Douglas DC-Y. Originally published in November 1991 as AAS 91-643, included in Proceedings of 5th ISCOPS, AAS Vol. 77, pages 329-351. TABLE OF CONTENTS 1. I NTRODUCTION 2.
Fig. 4 Potential SSTO Derived Vehicles In addition, the DC-Y will demonstrate three other critical technologies: qualification of a new main engine, reusability of cryogenic tanks and durability of the thermal protection system. Flight testing consists of initial suborbital flights expanding gradually to the first orbital flight

The Strategic Defense Initiative Organization does not "intend to develop this vehicle," said the SDIO source, referring to the operational DC-Y. "I think our mission with SSTO is to get it to a point, at the end of Phase-II when we fly something [the DC-X] and demonstrate the [short] turnaround, to where people will accept the fact that it can

It is pointed out that these studies are currently expected to lead to prototype hardware development aimed at demonstrating the SSTO This paper presents the analytical approach resulted from the conceptual development of the DC-Y composite cryotank, conducted under the NASA/Boeing NRA 8-12 Partnership, to support the continued progress of SSTO (Single-Stage-To-Orbit) concepts.

The 1990s rocket concept has now joined the Space Hall of Fame. Throttleable to 30% of thrust, sea level version of RL10. Four engines were built and were used on the DC-X and the upgraded DC-XA VTOVL SSTO launch vehicle demonstrators. The DC-Y was a conceptual vehicle design and did not use these engines.
Built for Ease of Use. SSTO vehicles are built to be operated like airliners. They can fly multiple times with no other maintenance needed other than refueling. The feasibility of single-stage-to-orbit (SSTO) is being demonstrated by a three-stage experimental vehicle test-flight scheme which will begin with the DC-X and DC-X2 suborbital vehicles and culminate with the DC-Y orbital launcher. While the DC-X would use comparatively heavy off-the-shelf hardware to explore operations-related issues, the DC-X2 would demonstrate lightweight structural Great work! Always loved the SSTO designs, impractical as though they may be with today's technology. Thanks for sharing the photos. Is the DC-Y the old (Estes?) model rocket kit, or did you get it from somewhere else?

Frontiers of Space The SSTO had to find a new mission, in order to have a new institutional home (and funding). Characterizing the SSTO vehicle as fulfilling military, civil, and commercial missions was not the answer, although it was the truth. It is one of only a few prototype SSTO vehicles ever built.
