T-1 Toroidal Aerospike "Dart" Liquid Fuel Engineは、すべての大気圧において燃焼効率が最も優れているという特徴をもった液体燃料エンジンである。

使用

エアロスパイクは推力重量比が良く、燃焼効率も比較的高い、変わったエンジンである。特徴的なノズルのおかげで、他のエンジンと違い、ほとんどどんな高度においても等しく効率的である。推力偏向はもたないが、この欠点を考慮に入れても、スペースプレーン用のエンジンとして基本的に最適な選択である。

これらの利点に加えて、全長が短いことも特筆できる。スペースプレーンが離陸するさい、後部に付けられたエンジンと滑走路との接触が避けられるからだ。また、同様に大気がある星への着陸船用エンジンとして、重量は増えるがLV-909 Liquid Fuel Engineの代用にも良い。

パーツ説明文

Toroidal AerospikeはC7 Aerospace社にとって大きなブレイクスルーです。旧モデルより重くはなっていますが、その頼もしい排気ノズルによってAerospikeはいかなる高度でも効率的な燃焼を行います。

トリビア

  • 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.
