Project ODYSSEY is launched for its first test flight! It had a stable flight up (Click on continue Reading to find the video). The recovery system failed and led to, as we like to call it, “an unplanned rapid disassembly”. The team plans to rebuild and launch again on May 9th.
MIT Rocket Team lost access to the blast chamber being used for testing the liquid engine, Pyralis, in February, so Project Pyralis is postponed indefinitely. The team still plans on competing in IREC this summer but with a commercial solid motor. The project is called Project Odyssey. Behind the name Odyssey Part of IREC competition…
We conducted our first hot fire test with the re-designed Pyralis engine and updated pre-burner. We flowed our pre-burner (air and hydrogen) for 20 seconds before flowing our main propellants. The engine ignites at about 22 seconds according to the timestamp in the video.
We conducted a water-flow test of our version 2 injector design. The injector uses a triplet impinging jet design to mix and atomize the propellants. This water-flow test video shows the injector producing a finely misted spray of water, validation the impinging jet design.
James, Matt and Connie have re-designed the supports that hold the nozzle spike into the combustion chamber of the Pyralis engine. The new support design will be more resilient to thermal expansion, vibration, and machining tolerances. Using this design will better control the nozzle’s throat area, leading to more consistent and predicable thrust.
We successfully tested the preburner for Pyralis today! The pre-burner acts like a pilot light during the engine start up sequence – the flames from the preburner will heat the combustion chamber, and will cause the main propellants to burn when they are flowed into the chamber. The pre-burner runs on propane and compressed air,…
Two of the three plates of our new injector design have been finished. The 24 fine holes of our triple impinging design can be seen on the bottom plate. The injector will be water flow tested in the coming weeks to make sure the design and manufacturing have correctly produced the desired fluid flow.
Zach B. and Jack E. have gotton our new spark igniter working, and it looks powerful! The spark will light propane and air in our preburner pilot light, and the preburner flame will in turn light the main propellants. The new spark electronics are much safer, simpler, and lighter than the previous designs.
Over the past months, the team has been re-designing the Pyralis engine. The new revision includes a pre-burner which will heat the engine before ignition; we expect this change to resolve engine start-up issues experienced on the first engine design. We have also modified the injector to include better seals and orifices which can be…
We tested the injector of our Pyralis rocket engine by flowing water into it at 1200 psi (8.3 MPa). The test qualitatively shows good mixing and atomization of the propellant streams.
