There has been and continues to be significant discussion about the viability of fully reusable, single-stage-to-orbit (ssto) concepts for delivery of payloads to orbit. Nofbx™ single stage to orbit mars ascent vehicle outlined herein is a description of a mars ascent single stage to orbit (ssto) nofbx™ vehicle one propellant and propulsion system. Any different single-stage to orbit (ssto) launch vehicle concepts have been proposed in the search for a space shuttle replacement each of these vehicles had promised to reduce costs, turn around time, and. The launch vehicle is an all-electric single stage to orbit (ssto) spaceplane, using a system and liquid oxygen second generation emdrive propulsion. The venturestar was a single stage to orbit ship that used an aerospike rocket engine it had a proposed carbon composite structure much like the haas 2ca the x-33 was the concept demonstrator.
A single-stage-to-orbit (or ssto) vehicle reaches orbit from the surface of a body without jettisoning hardware, expending only propellants and fluids the term usually, but not exclusively, refers to reusable vehicles. At a time when space budgets are limited and other systems are looking to reduce cost to orbit through limited re-usability (see spacex) or air launched two-stage to orbit systems (see stratolaunch), it's difficult to see an ssto happening anytime soon. Engine technology provides a single state to orbit (ssto) ascent vehicle design option with significant benefits over solid and storable liquid propulsion ap.
Notable single stage to orbit research spacecraft include skylon, the dc-x, the lockheed martin x-33, and the roton ssto however, despite showing some promise, none of them has come close to achieving orbit yet due to problems with finding the most efficient propulsion system. A two-stage-to-orbit (tsto) or two-stage rocket launch vehicle is a spacecraft in which two distinct stages provide propulsion consecutively in order to achieve orbital velocity it is intermediate between a three-stage-to-orbit launcher and a hypothetical single-stage-to-orbit (ssto) launcher. He principal hope for achieving single-stage to orbit (ssto) with a practically-useful payload mass fraction is seen to be the development of hybrid propulsion technology that exploits, at least at low to intermediate. The quest for a single-stage-to-orbit spaceship, or ssto, has bedeviled aerospace engineers for decades nasa's deputy associate administrator for exploration systems development, who spent.
I would call the space shuttle a 15 stage to orbit, where it went all the way to orbit on the same main propulsion system and tanks, but dropped two entire booster propulsion systems on the way up, which were a significant fraction of the mass at launch. Single-stage-to-orbit (ssto) could an ssto with conventional propulsion (non air-breathing, non-nuclear, no exotic fuels) use refractory metal heat shielding, or would the weight penalty simply be too great. Introduction to aerospike and its aerodynamic features single stage to orbit (ssto), - ver since jet and rocket propulsion systems have emerged. Single-stage-to-orbit (ssto) systems are being studied as potential launch vehicle concepts for the time period following space shuttle on the basis of projected advance.
Propulsion system weight the application of scramjet engine technology as part of combined cycle propulsion systems is also being pursued under nasa and us air force sponsorship. The fully developed version was to be called venturestar and was to be a fully reusable single stage to orbit spacecraft nasa abandoned the project in 2001 the quest to build a single stage. Upon reaching orbit, the payload is released, possibly to be propelled to higher orbit by its own propulsion system, while the spaceplane re-enters the atmosphere, glides to the vicinity of an airport, and then lands in either an unpowered or rocket or jet powered mode. The delta clipper was an unmanned demonstrator launch vehicle flown from 1993 to 1996 for testing vertical takeoff and landing (vtol) single-stage to orbit (ssto) technology. Such a reusable single-stage-to-orbit (ssto) craft might finally enable regular, truly affordable access to space but a practical ssto vehicle is no easy objective.
Single-stage-to-orbit (ssto) on its own merit3 in 1994, while the orbiter propulsion system is a conventional liquid oxygen (lox)thydrogen rocket engine. These technical revolutions may allow what has been considered largely impractical: a chemical earth-to-orbit rocket without stages, a single-stage-to-orbit vehicle, or ssto a rocket without stages could be amazingly simple, making it inexpensive and reliable to operate. A comparison of propulsion concepts for ssto reusable launchers r varvill a bond (2003), jbis, 56, 108-117 refcode: 200356108 keywords: reusable launchers, sabre, skylon, ssto abstract: this paper discusses the relevant selection criteria for a single stage to orbit (ssto) propulsion system and then reviews the characteristics of the typical engine types proposed for this role against.

Abstract this paper discusses the relevant selection criteria for a single stage to orbit (ssto) propulsion system and then reviews the characteristics of the typical engine types proposed for this role against these criteria. Theory of aerospace propulsion, second edition, teaches engineering students how to utilize the fundamental principles of fluid mechanics and thermodynamics to analyze aircraft engines, understand the common gas turbine aircraft propulsion systems, be able to determine the applicability of each, perform system studies of aircraft engine systems.
