The RE-J10 Wolfhound liquid fuel engine is an efficient upper stage engine.
Usage
The Wolfhound's vacuum specific impulse is significantly higher than any other stock/DLC bipropellant engine, making it one of the most effective engines for deep space travel.
It has higher thrust, but a lower thrust-to-weight ratio, than other vacuum-oriented bipropellant engines such as the Poodle and Terrier. So to some extent the Wolfhound bridges the gap between those engines and the liquid-fuel-only Nerv, which has a much higher Isp and much lower TWR.
Product description
| “ | Woof! With the largest bell for its size, this upper stage engine will leave your ears ringing. — Rockomax Conglomerate |
” |
Variants
As of version 1.4.1 this engine has two models that can be switched in the editor.
Trivia
Real-world comparison
The Wolfhound was inspired by the American AJ10-137 engine used for the Apollo SPS. Other variants of the AJ10 were also used for the Space Shuttle's Orbital Maneuvering System and on the Orion service module.
Unlike the Wolfhound, the AJ10 engines are quite lightweight, and they don't have exceptional specific impulse. (Rather than the liquid hydrogen, they use less energy-dense hydrazine-based hypergolic fuels, for storage and reliable multiple firings on longer missions.)
Changes
- Renamed from 'RE-J10 "Wolfhound" Liquid Fuel Engine AJ10' to 'RE-J10 "Wolfhound" Liquid Fuel Engine'
- Moved tech from Heavy Rocketry to Very Heavy Rocketry
- Increased unlock cost from 6200 to 12000
- Increased cost from 1680 to 3000
- Increased mass from 2.5 to 3.3
- Improved Isp
- Added ModuleTestSubject
- Initial Release
