It has been a while since I have posted something from the Boston University Rocket Propulsion Group, so it is always good to get some new updates from the team.
The Horizontal Test Stand (HTS), built 2017/2018 is capable of taking engines up to 10,000 lbf (44,482 N) and provides for a much more capable test stand than the vertical set up the team had used before.
The team are still aiming for the Karman line, so hopefully, 2019 is the year it builds up to!
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.
