Flight Test
Flight testing is a branch of aeronautical engineering that develops specialist equipment required for testing aircraft behaviour and systems. Instrumentation systems are developed using proprietary transducers and data acquisition systems. Data is sampled during the flight of an aircraft, or atmospheric testing of launch vehicles and reusable spacecraft. This data is validated for accuracy and analyzed before being passed to specialist engineering groups for further analysis to validate the design of the vehicle. The flight test phase accomplishes two major tasks: 1) finding and fixing any design problems and then 2) verifying and documenting the vehicle capabilities for government certification or customer acceptance. The flight test phase can range from the test of a single new system for an existing vehicle to the complete development and certification of a new aircraft, launch vehicle, or reusable spacecraft. Therefore, the duration of a particular flight test program ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atmospheric Reentry
Atmospheric entry is the movement of an object from outer space into and through the gases of an atmosphere of a planet, dwarf planet, or natural satellite. There are two main types of atmospheric entry: ''uncontrolled entry'', such as the entry of astronomical objects, space debris, or bolides; and ''controlled entry'' (or ''reentry'') of a spacecraft capable of being navigated or following a predetermined course. Technologies and procedures allowing the controlled atmospheric ''entry, descent, and landing'' of spacecraft are collectively termed as ''EDL''. Objects entering an atmosphere experience atmospheric drag, which puts mechanical stress on the object, and aerodynamic heating—caused mostly by compression of the air in front of the object, but also by drag. These forces can cause loss of mass ( ablation) or even complete disintegration of smaller objects, and objects with lower compressive strength can explode. Crewed space vehicles must be slowed to subsonic s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

SpaceX Starship First Integrated Flight Test
Starship flight test 1 was the maiden flight of the integrated SpaceX Starship launch vehicle. SpaceX performed the flight test on April 20, 2023. The prototype vehicle was destroyed less than four minutes after lifting off from the SpaceX Starbase in Boca Chica, Texas. The vehicle became the most powerful rocket ever flown, breaking the half-century-old record held by the Soviet Union's N1 rocket. The launch was the first "integrated flight test," meaning it was the first time that both the Super Heavy booster and the Starship spacecraft flew together as a fully integrated Starship launch vehicle. The launch was part of SpaceX's Starship development program, which follows an iterative and incremental approach involving frequent, and often destructive, test flights of prototype vehicles. Before the launch, SpaceX officials said they would measure the mission's success "by how much we can learn" and that various planned mission events "are not required for a successf ...

Separation Event
A multistage rocket or step rocket is a launch vehicle that uses two or more rocket ''stages'', each of which contains its own engines and propellant. A ''tandem'' or ''serial'' stage is mounted on top of another stage; a ''parallel'' stage is attached alongside another stage. The result is effectively two or more rockets stacked on top of or attached next to each other. Two-stage rockets are quite common, but rockets with as many as five separate stages have been successfully launched. By jettisoning stages when they run out of propellant, the mass of the remaining rocket is decreased. Each successive stage can also be optimized for its specific operating conditions, such as decreased atmospheric pressure at higher altitudes. This ''staging'' allows the thrust of the remaining stages to more easily accelerate the rocket to its final speed and height. In serial or tandem staging schemes, the first stage is at the bottom and is usually the largest, the second stage and subseq ...

SpaceX Super Heavy
Super Heavy is the first stage of the SpaceX Starship super heavy-lift launch vehicle, which it composes in combination with the Starship second-stage. As of 2023, Super Heavy prototypes are being flight tested. In April 2023, Super Heavy flew for the first time on the first orbital launch attempt of the Starship rocket. Manufacturing According to Eric Berger of ''Ars Technica'', the manufacturing process starts with rolls of steel, which are unrolled, cut, and welded along the cut edge to create a cylinder of 9 m (30 ft) in diameter, 1.82 m (6 ft) in height, and 4 mm (0.16 in) thick, and around 1,600 kg (4,000 lb) in mass. These cylinders, are stacked and welded along their edges to form the outer layer of the rocket. Inside, the methane and oxygen tanks are separated by robot-made domes. Before final assembly, grid fins are added to the interstage, and the chines are added after stacking of the propellant tanks. Design The first-stage Super Heavy booster is tall, ...

SpaceX Raptor
Raptor is a family of full-flow staged-combustion-cycle rocket engines developed and manufactured by SpaceX for use on the in-development SpaceX Starship. The engine is powered by cryogenic liquid methane and liquid oxygen ("methalox") rather than the RP-1 and liquid oxygen ("kerolox") used in SpaceX's prior Merlin and Kestrel rocket engines. The Raptor engine has more than twice the thrust of SpaceX's Merlin 1D engine that powers the Falcon 9 and Falcon Heavy launch vehicles. Raptor is used in the Starship system in both the super-heavy-lift Super Heavy booster and in the Starship spacecraft which acts as the second stage when launched from Earth and as an independent spacecraft in LEO and beyond. Starship is planned to be used in various applications, including Earth-orbit satellite delivery, deployment of a large portion of SpaceX's Starlink satellite constellation, exploration, Moon landing, and colonization of Mars.
