Usage
The Thud is a liquid fuel engine with thrust vector control that allows efficient control of the rocket during descent and landing. The Thud is fairly low-thrust. This is offset by its comparatively low weight, however. The engine has a thrust-to-weight ratio comparable to the LV-T45 "Swivel" Liquid Fuel Engine.
The low thrust and radial mounting makes a single Thud unsuitable as a main engine on most lower stages, but it can be used to augment other engines. A common use of this engine is in lander designs, as it eliminates the need to have a vulnerable engine in an easily-damaged position. The Isp of this engine is adequate, being 275 s at 1 atm and 305 s in vacuum, not far behind the LV-T30 "Reliant" Liquid Fuel Engine and LV-T45; however, it is still greatly inferior to dedicated vacuum engines, such as the LV-909 "Terrier" Liquid Fuel Engine and the RE-L10 "Poodle" Liquid Fuel Engine.
Additionally, landing legs can be mounted directly on these engines. This is an advantage shared with other radial engines: the LV-1R "Spider" Liquid Fuel Engine, the 24-77 "Twitch" Liquid Fuel Engine and the O-10 "Puff" MonoPropellant Fuel Engine.
Like the Twitch, this engine has a respectable gimbal range of 8 degrees.
Contrary to the product description, it can indeed use fuel from rocket fuel tanks that use non-Rockomax engines as well as ones from that company.
Trivia
- The Thud bears a slight resemblance to the Space Shuttle's Orbital Maneuvering System (OMS) thrusters. However, besides obvious coloration differences, the Thud uses liquid fuel and oxidizer, unlike the real life OMS thrusters which burned hypergolic bipropellant fuel.
