Interstellar Technologies have been continuing testing of their LOX/Ethanol engine for their MOMO sub-orbital rocket, most recently pulling off this 120sec burn.
The engine is ablative and uses a graphite nozzle, as you will see it gets pretty hot! Judging by the exhaust plume, it looks to be a nice burn from start to finish.
An interesting talk from Gilmour Space Tech. Gilmour is developing a small satellite launcher using hybrid rocket motors, more specifically powered by Hydrogen Peroxide and their own 3D printed fuel grains.
Tim Draper talks with Nadir Bagaveyev, CEO of Bagaveev Corp. Focused on launching nanosatellites, Bagaveev Corp became the first in the world to fly a 3D printed rocket engine in 2015 and are next scheduled to fly out of Black Rock, Nevada at the end of August this year.
Video Caption: In this episode of the Startup Hero, Tim talks with Nadir Bagaveyev, the CEO & Founder of the BAGAVEEV CORPORATION. His corporation is currently focused on launching nanosatellites so small teams can innovate in space and grow into large teams and large satellite companies.
Nadir is a Aerospace engineer graduated from Embry-Riddle Aeronautical University, veteran US Army Officer. Born in Russia, Nadir has learned aerospace design philosophies of both countries to implement the best practices or commercial space development.
RPA (Rocket Propulsion Analysis) is the tool to own for liquid fuelled rocket engine design.
Although, having been around for a while, downloading the latest update I thought it may make a good post to talk about for those who have never come across it.
Basically, RPA allows you to design your liquid rocket engine from the ground up, carrying out performance analysis, chamber sizing, chamber cooling analysis to name a few of the features.
It is very easy to use and allows quick design and iteration of your rocket engine and can also export a .dxf file of the inner engine geometry for further CAD design.
It can be downloaded as a trial in the lite edition but I would highly recommend buying a full version, it will be an investment you would not regret.
