That's why Rocket Lab is working to try to save and reuse its first stage boosters.The company SpaceX already has a system for reusing boosters. Using special engines, SpaceX's Falcon 9 rocket boosters slow themselves down as they fall to Earth, and land in a controlled way.But Rocket ...
Among these there are models for the parachute geometry, mass properties, deployment, inflation, opening force, area oscillations, aerodynamic coefficients, apparent mass, interaction with the main landing engines, and offloading. These models were kept as simple as possible, considering the overall ...
In other cases, a gas such as hydrogen is first turned into a plasma and then ionized and accelerated. As attractive as some of these ideas sound in theory, they have thus far found relatively few practical applications in the construction of rocket engines. ...
FIELD: astronautics.SUBSTANCE: invention relates to rocket engineering and particularly to multi-stage rockets and can be used in rocket engineering. Proposed device comprises main acceleration unit represented by case and head fairing. Afterwards, compartment for payload, fuel tanks connected with rocket...
This is a time when you want the engines to cut off! NASA - National Aeronautics and Space Administration It’s been one of the most famous acronyms in the world since the agency was formed 65 years ago on July 29, 1958 and succeeded the National Advisory Committee for Aeronautics (NACA)...
In contrast, a controlled re-entry is performed by using an engine burn that directs the rocket body to a remote area of ocean or a recovery zone. Some fuel must be retained in the rocket body for this purpose, and the engines must be able to reignite. ...
Rhenium is mainly used in the production of aero-engine blades, high-precision equipment such as the gyroscope, synthesis of high-octane gasoline, and about 80% of the world's rhenium is used in the production of aviation engines. Rhenium is used for high-temperature coating on rockets and ...
SpaceXbriefly fired the nine first-stage engines of a previously flown Falcon 9 first stage rocket Monday in a dramatic pre-flight test to clear the way for launch of an SES communications satellite Thursday. The launching will mark the first flight of a “used” booster, a key element in...
TW Moss,WJ Bowman - 《Journal of Spacecraft & Rockets》 被引量: 9发表: 1971年 Modeling and Fluid Flow Analysis of Wavy Fin Based Automotive Radiator In continuous technological development, an automotive industry has increased the demand for high efficiencyengines. A high efficiency engines in no...
The term “maintenance” refers to preventive maintenance, alterations and repairs, and introduction of ADs. Airworthiness should depend on the maintenance programs, which also establishes the replacement of time change items, the overhaul of engines, propellers, and various parts and appliances. In Ch...
