A few updates from Boston University Rocket Propulsion Group as they work on their newest rocket, LAD.
Boston University Rocket Propulsion Group recently test fired their Iron Lotus rocket engine. Developing ~2500lbf (11.1kN) of thrust, the engine was tested for 1 and 3sec burn times.
As the name implies, the engine is a steel heat sink engine, not intended for long duration firing and primarily used for ignition testing, before the (flight) regen Lotus Dev 2 engine is tested.
That sound and echo are impressive!!
Video Caption: February 26, 2017 cold flow test of the Lotus Dev 2 injector mounted on the Iron Lotus combustion chamber. Data from this test is used for hot fire ignition and shutdown timing.
Lotus Dev 2 is a 2,500 lbf liquid engine capable of powering the Starscraper launch vehicle into suborbital space. Iron Lotus is a heat sink engine used for low risk ignition testing.
Lotus Dev 2 is also making progress, should be spectacular seeing this make fire!!
BURPG attempted a static fire test of their Iron Lotus this past weekend but were unfortunately hampered by a stuck pre-valve on the oxidizer side of the system.
Iron Lotus is a steel heat sink version of the teams Lotus Dev 2 engine, designed to produce 2,500lbf at sea level, the Dev 2 will power the teams Starscrapper rocket on a suborbital trajectory.
