Interstellar Technologies Gas Generator and Attitude Control Testing

I missed these latest videos from Interstellar Technologies, the first one showcases gas generator static tests using a combination of liquid oxygen and kerosene. Although the team’s Momo suborbital sounding rocket will use a gas pressurized feed system, I guess a turbopump system will be required for their orbital launcher plans.

The second video showcases the team’s experiments in attitude control, refining their system for controlled flight (from a couple of years ago).

IST LEAP Flight Progression

Interstellar Technologies Inc. who are working towards a guided suborbital rocket flight (Momo) and eventually a small satellite launcher, have recently been making progress with their control system experimentations.
LEAP or Flight test for attitude control is a vertical take off lunar landing looking rocket that has been designed to test the team’s control system. Four flights have been carried out so far, and as can be seen in the video’s below, steady progress has been made.

Although not new video’s, I thought it was worth posting as it is interesting to watch and see the teams progression to date.

Hard Starts

Something different, a recent video from Interstellar Technologies Inc, shows one of their liquid fuelled rocket engines having a hard start. Try and spot the chamber exiting!

A hard start refers to the tendency in liquid bipropellant engines to get very high pressure spikes during ignition. From Space Propulsion Analysis and Design.
