ABout

Lotus Dev 1 (LD1) is the first liquid engine developed by the Boston University Rocket Propulsion Group. The design features a copper chamber and injector with an aluminum jacket and saddle.  LD1 produced valuable data for the Lotus liquid engine development program, and has paved the way for Lotus Dev 2 and a Starscraper sub-orbital space flight.
