It's held up vertical by a PVC pipe and wooden centreing ring, it's held up vertical in case of the nozzle blow out so the nozzle doesn't hit anything or anyone. Uses a pressure transducer the measure chamber pressure and that is in turn used to calculate Motor thrust and Isp etc on a spreesheet.
The pressure transducer is a MSP 2K5, good for psi. The great thing is I don't need an amp for the transducer. The equation was given to me in a manual I read on using the transducer in a strand burner. I machined the bulkhead and brass tube and transducer adaptor on my lathe, the gas flow at the bulkhead is reasonably static compared to the nozzle end, so the chamber pressure pressurises the air in between the chamber and transducer, that air heats up, that's why the long tube is made from brass in order to absorb that heat.
I have fired this set up in a "K" Ns motor, straight after firing the transducer is barely Luke warm. I use this set up to test my own experimental formulation, based on either Ammonium Perchlorate and polyurethane or silicone rubber based propellants, these are all for just my general hobby use.
I am currently working on an "M" motor 8,Ns The engine is buried as usual, although the Transducer is covered by an aluminium "strut" that covers the transducer and diverts the thrust away into the ground. Here's a picture of a thrust curve of H engine and the K motor firing. The nozzle entrance volume was simulated by an additional chamber.
Nozzle and chamber assembly were of mild steel.
A 2 mm thick fuel layer was sealed to the chamber wall. The investigation of ignition behavior, combustion stability and performance of the testbed with the rocket oxidizer feed unit was performed with this version. Four test firings were performed.

Includes daily news posts, guest opinion and more. Students - when we compare one thing to something else, it helps our brains and souls take a mental leap. By placing two different things near each other, two things which share some quality, a reader can see a connection and understand a new idea or image more clearly.
