Quad (rocket)
In rocketry, the Armadillo Aerospace Quad vehicle called Pixel is a computer-controlled VTVL rocket that was used in 2006 to compete in the Lunar Lander Challenge. General description The quad vehicle design is a pressure fed in blow-down mode from an initial pressure of 320 psi for level 1 (400 psi level 2). The cold gas vernier engines are cross-fed by gas drawn from ullage space of the opposite tank. The vehicle was able to transfer propellant through connecting pipes between opposite tanks by controlling ullage pressures with the thrusters; this helps it balance, minimizing gas use. The main engine had two-axis thrust vectoring. The vehicle was fully computer controlled; with guidance from GPS and fiber optic gyros. Specification The specification for Pixel/Texel for level 1: * Width: ~1.9 m (~75 inches) * Height: ~1.9 m (~75 inches) * Dry Weight: 650 pounds * Gross Lift Off Weight (GLOW): ~1500 pounds (360 pounds ethanol, ~500 LOX) * Payload: 55 pounds * Engines: 1 (+ 4 c ...

Rockets And Missiles
A rocket (from it, rocchetto, , bobbin/spool) is a vehicle that uses jet propulsion to Acceleration, accelerate without using the surrounding Atmosphere of Earth, air. A rocket engine produces thrust by Reaction (physics), reaction to exhaust expelled at high speed. Rocket engines work entirely from rocket propellant, propellant carried within the vehicle; therefore a rocket can fly in the vacuum of space. Rockets work more efficiently in a vacuum and incur a loss of thrust due to the opposing pressure of the atmosphere. Multistage rockets are capable of attaining escape velocity from Earth and therefore can achieve unlimited maximum altitude. Compared with Airbreathing jet engine, airbreathing engines, rockets are lightweight and powerful and capable of generating large accelerations. To control their flight, rockets rely on momentum, airfoils, Reaction control system, auxiliary reaction engines, gimballed thrust, Reaction wheel, momentum wheels, Thrust vectoring, deflection o ...

Grasshopper (rocket)
Falcon 9 prototypes were experimental flight test Reusable launch system, reusable rockets that performed VTVL, vertical takeoffs and landings. The project was private capital, privately funded by SpaceX, with no funds provided by any government until later on. Two prototypes were built, and both were launched from the ground. The earliest prototype was ''Grasshopper''. It was announced in 2011 and began low-altitude, low-velocity hover/landing testing in 2012. ''Grasshopper'' was tall and made eight successful test flights in 2012 and 2013 before being retired. A second prototype of Falcon 9 was the larger and more capable Falcon 9 Reusable Development Vehicle (F9R Dev, also known as F9R Dev1) based on the Falcon 9 v1.1 launch vehicle. It was tested at higher altitudes and was capable of much higher velocity but was never tested at high velocity. The F9R Dev1 vehicle was built in 2013–2014 and made its first low-altitude flight test on 17 April 2014; it was lost during a three ...

CORONA (SSTO)
CORONA is a single-stage-to-orbit launch vehicle capable of performing vertical takeoff and landing. It was developed by OAO GRTs Makeyev from 1992 to 2012. However, the development was declined due to lack of funding. In 2016, the company announced plans to resume the development of the CORONA vehicle. Overview CORONA is intended for launching payloads to low Earth orbit with an altitude of . It has a launch mass of and is intended for launching payloads weighing up to with traditional use or up to with a special scheme for launching into low Earth orbit. However, the payload capacity goes down to and up to respectively when launching from Russia. With the use of reusable boosters that form a launch complex with it, the launch vehicle provides launching into orbits with an inclination of up to 110° up to altitudes of and returning from them if necessary.

Zarya (spacecraft)
The Zarya spacecraft () was a secret Soviet project of the late 1980s aiming to design and build a large crewed vertical-takeoff, vertical-landing (VTVL) reusable space capsule, a much larger replacement for the Soyuz (spacecraft). The project was developed during 1985–1989 years by Energia corporation until it was shelved in 1989, "on the eve of the Soviet Union's collapse" due to lack of funding. The name of the project was later reused by the Zarya space station module which served as the first component of International Space Station in 1998. Design The Zarya spacecraft would have differed from all previous spacecraft by having an array of a dozen rocket engines for making a soft landing upon return to Earth, without using a parachute. Mission Zarya spacecraft would have brought crew and supplies to ''Mir'' or supplies only in automated mode. It would have had a normal crew of one or two and offered the possibility of carrying a maximum of eight to twelve if used as ...

McDonnell Douglas DC-X
The DC-X, short for Delta Clipper or Delta Clipper Experimental, was an uncrewed prototype of a reusable single-stage-to-orbit launch vehicle built by McDonnell Douglas in conjunction with the United States Department of Defense's Strategic Defense Initiative Organization (SDIO) from 1991 to 1993. Starting 1994 until 1995, testing continued through funding of the US civil space agency NASA. In 1996, the DC-X technology was completely transferred to NASA, which upgraded the design for improved performance to create the DC-XA. Background According to writer Jerry Pournelle: "DC-X was conceived in my living room and sold to National Space Council Chairman Dan Quayle by General Graham, Max Hunter and me." According to Max Hunter, however, he had tried hard to convince Lockheed Martin of the concept's value for several years before he retired. Hunter had written a paper in 1985 entitled "The Opportunity", detailing the concept of a Single-Stage-To-Orbit spacecraft built with low- ...
