machining a graphite rocket nozzle for hybrid rocket -

Nozzle Design

The nozzle will have a conical profile due to its proven performance and ease of manufacture. The throat was designed with a diameter of 0.1875 inches based on the size limitations placed on the nozzle by the structural components. Following Rocket Propulsion Elements' guideline, the exit diameter of the divergent nozzle is five times the throat diameter, 0.9375 inches.

2020/2/24I mill and lathe graphite regularly.(almost every day)The grade is very important. The finer the grain size, the better. Depending on the shape, size and cross section, you must do things differently when machining carbon. If you have very thin areas, you need to be

Investigation of Graphite Nozzle Erosion in Hybrid

2020/3/30A recently developed reconstruction technique is used to investigate graphite nozzle erosion in two scales of hybrid rocket motors, 30-N-thrust class and 2000-N-thrust class, using oxygen as the oxidizer and high-density polyethylene as the fuel. Thermocouple

Numerical and experimental study of the

2019/2/1Hybrid rocket motors is a promising propulsion system because of its intrinsic advantages over a conventional solid rocket motor and liquid rocket engine. However, serious nozzle erosion is a key problem that prevents hybrid rocket motors from being widely used, especially for propulsion systems with long operating times.

What type of graphite is best for making small rocket

I want to make a small rocket nozzle (1.5 OD) and need to know what type of graphite I should buy. I want something strong that machines well I can't recommend a material, but watch out when machining graphite. The dust will get everywhere. It can get inside

3D carbon

The need to increase the payload capacity of the current launchers drives rocket engine manufacturers to seek higher thrust level, specific impulse and thrust to weight ratio. The use of high temperature C-C composite materials is an efficient way to reach these objectives by allowing use of high expansion ratio nozzle extensions benefiting of the outstanding thermal, mechanical and fatigue

Development of a Reusable Aerospike Nozzle for Hybrid Rocket

The potential for hybrid rocket motors was clearly demonstrated in 2004, when SpaceShipOne won the Ansari X-Prize using an air-launched space vehicle powered by an N 2 O -HTPB hybrid rocket motor. v On July 26, 2007, a fatal accident during a cold-flow test of

Richard Nakka's Experimental Rocketry Site

Without a doubt, machining a rocket nozzle is a challenge, especially for those who have had limited experience in metal working. Machining a nozzle draws upon some of the more difficult aspects of lathe use, owing to the rather complex shape and need for accuracy, combined with the desire of producing a lightweight nozzle having all or most excess material cut away.

Making graphite nozzles with powder and some sort of

At least where I'm from, blocks of graphite for machining are extremely expensive and hard to find. I was wondering perhaps it I could make a metal nozzle then line the inside with graphite somehow. I was thinking making a paste of graphite and perhaps epoxy and letting it cure on the inside of the nozzle, then machining it smooth and uniform.

Build a High Power Rocket Nozzle : 13 Steps (with

A lathe is required for making rocket nozzles. You can get by without a lot of the tools I will use, but not without a lathe. I own two lathes, but because of the mess made by graphite, I only use the cheap Harbor Freight 7 x 10 mini-lathe for making rocket nozzles.
