Тороидальный ракетный аэрошип (англ. "Toroidal Aerospike Rocket - это жидкотопливный двигатель с уникальной особенностью: практически полной независимостью от атмосферного давления.

Использование

The aerospike rocket is an unusual rocket engine with intermediate thrust-to-weight ratio, and relatively high fuel efficiency. Thanks to its unique nozzle, it is almost equally effective at all altitudes unlike other engines. It has two important drawbacks: it cannot be stacked directly above other parts, and it does not have any thrust vectoring. Despite these drawbacks, it is still usually the best choice for a main engine when building spaceplanes.

An added advantage in this application is that aerospikes are also quite short, which can help reduce the risk of collision with the runway during takeoff when the engine is mounted at the rear of a spaceplane. Another advantage is that the short length makes it a good alternative for the LV-909 Liquid Fuel Engine on landers, when more thrust is required or the landing takes place in an atmosphere, though it is heavier than the LV-909.

Описание изделия

« The Toroidal Aerospike is a huge breakthrough from C7 Aerospace. While heavier than previous models, with its heavy-duty exhaust nozzle, the Aerospile makes up for it with an efficient burning of fuel at all altitudes.  »

Trivia

  • In real life, the heavy aerospike nozzle is an advanced alternative to the classic hourglass-shaped De Laval nozzles sported by the LVT engines. The bell of a rocket nozzle contains and accelerates the supersonic exhaust gas, converting exhaust pressure into velocity along its length. The longer the nozzle, the lower the final pressure becomes. However, in an atmosphere the exhaust stream interacts with the air around it, and if its pressure falls too low in comparison the stream can become unstable and inefficient. In a vacuum, an ideal nozzle has an infinite length, but practically nozzle length is a tradeoff - shorter nozzles can handle thicker atmosphere, but don't generate the exhaust velocity of longer ones. An aerospike provides comparable performance to a De Laval nozzle in space, but at lower altitudes it can be 20-30% more efficient.
  • In versions 0.15, and 0.16, the aerospike had the highest Isp of any stock engine. In versions 0.16 and 0.17, the aerospike had the highest TWR of any stock liquid fuel engine. As a result of these features, it benefited more from the throttle bug than any other engine. Between versions 0.18 and 0.21.1, a large chunk of the part.cfg was missing, resulting in the aerospike having default drag, maxtemp, and impact tolerance. This caused odd behavior under some circumstances.
