This time with better info. So we experimented with pintile placement using a simple system just to get some initial data. In order to avoid things like combustion instability and to allow for film cooling, achieving a good fuel mixture is critical for the success of our project. Our first one has a clear gap …
Two quick takes from a mixture test of our injector design.
But still fun. Here's a slow pan of the redesigned flight rocket. https://youtu.be/YmAoEE-PN4Q
So I spent some time re-inventing the wheel to create a light weight simple recovery mechanism. This model is missing a few elements, but basically our proposed recovery mechanism works as follows: A single actuator moves a pin through a tab mounted securely to the central pin. On the far side of the motion the …
Here are some pretty pictures. The first is a mockup of a model I'm currently running CFD on to assess if and how a nosecone modeled on a Kingfisher beak might reduce our pressure drag. Japan Railways Group modeled their latest bullet trains off of this beak and saw some pretty impressive results which you …
Introduction The 2017-2018 Talon team is responsible for all aspects of testing besides the design of the engine itself. To safely test engine designs, we are going to build an engine testing facility. It will consist of a test stand and propellant feed system mounted on a trailer, a control center at a safe distance …
This’ll be the first time OTRA has posted an update on our website! Woohoo! Today I’d like to give a tidbit into where we are at in engine design. I won’t be covering everything we have, but I’d like to share a bit of how we approached the cooling and stresses in the combustion chamber. …
