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。



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。


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。

  • 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.


Appearance before 1.0.5
  • Remodeled and retextured
  • Now it can be stacked above other parts
  • Mass reduced from 1.5 to 1.0
  • New description
  • Missing part.cfg lines restored: drag is now 0.2, impact tolerance is now 20 m/s, and maximum temperature is now 3600 K.
  • Alternator added, engine now generates 5.0 electric charge per second.
  • cost increased from 850 to 3850
  • Part now uses fuel and oxidizer. Thrust reduced (250 -> 175), Sea level Isp reduced (390 -> 388), mass increased (1 -> 1.5)
  • (Accidental) drag value (0.2) removed, defaults to 0.1
  • (Accidental) impact tolerance value (20) removed, defaults to 9
  • (Accidental) maximum temperature value (3600) removed, defaults to 3400
  • Changed part type from LiquidEngine (mass 2.5, thrust 225, fuel consumption 7.6) to LiquidFuelEngine (mass 1, thrust 250, Isp 390)
  • Initial Release
