Jet Turbine Engine: February 2007

http://jetturbine.blogspot.com/2007_02_01_archive.html

This is an ongoing record of my struggles to make a functioning jet engine from scratch. It isn't done yet so don't expect to find a full 'how to do it' plan, but I'm getting there. Shots from the archive. Friday, 2 February 2007. The overall size of the engine is dictated by the diameter of the turbine and compressor wheels. I settled on a diameter of 60mm with a blade height of 10mm for the turbine because this seems a reasonable size and I have a circular ss blank of that diameter. When the air leaves...

Jet Turbine Engine: I got it! I got it! - - - I don't got it! (groan)

This is an ongoing record of my struggles to make a functioning jet engine from scratch. It isn't done yet so don't expect to find a full 'how to do it' plan, but I'm getting there. Shots from the archive. Wednesday, 23 April 2008. I don't got it! So what's happenin' Dude? I hear you ask. Well, I almost had it running - but you've heard that story before? The plot of power versus temperature exactly parallels the theoretical calculation. Except for two effects. The second effect is a similar frictional l...

Jet Turbine Engine: January 2008

http://jetturbine.blogspot.com/2008_01_01_archive.html

This is an ongoing record of my struggles to make a functioning jet engine from scratch. It isn't done yet so don't expect to find a full 'how to do it' plan, but I'm getting there. Shots from the archive. Tuesday, 29 January 2008. The blower I made from an old vacuum cleaner is quite powerful, in fact it gives a noticeable thrust on it's own. That came out as 0.62 Newtons. Knowing the diameter of the outlet (45mm : 0.0016m. The turbine cross-section area is also 0.0016 m. Fed the blower output into a 50...

Jet Turbine Engine: A Practical Jet Engine

http://jetturbine.blogspot.com/2007/02/practical-jet-engine.html

This is an ongoing record of my struggles to make a functioning jet engine from scratch. It isn't done yet so don't expect to find a full 'how to do it' plan, but I'm getting there. Shots from the archive. Thursday, 1 February 2007. A Practical Jet Engine. This is the layout of a simple but entirely practical jet engine showing the essential parts. The purpose of the diffuser is to collect the air from the compressor, slow it down, and guide it into the combustion chamber as smoothly as possible. For the...

Jet Turbine Engine: February 2008

This is an ongoing record of my struggles to make a functioning jet engine from scratch. It isn't done yet so don't expect to find a full 'how to do it' plan, but I'm getting there. Shots from the archive. Wednesday, 27 February 2008. If it doesn't work, fiddle with it. Spinning up' the turbine with an air blast is a pretty effective way to start it, but when it comes to making careful measurements, the fact that something is forcing air into the engine gives a problem. It's interesting to note that powe...

Jet Turbine Engine: How a jet turbine engine works

http://jetturbine.blogspot.com/2008/02/how-jet-turbine-engine-works.html

This is an ongoing record of my struggles to make a functioning jet engine from scratch. It isn't done yet so don't expect to find a full 'how to do it' plan, but I'm getting there. Shots from the archive. Thursday, 1 February 2007. How a jet turbine engine works. I have always been fascinated by jet engines. Part of that fascination being that I could never understand how they could possibly work. The two fans are connected together so that the rear one drives the front one, sucking in more air. The rea...

Jet Turbine Engine: A Homemade jet engine (The journey begins)

http://jetturbine.blogspot.com/2008/01/homemade-jet-engine.html

This is an ongoing record of my struggles to make a functioning jet engine from scratch. It isn't done yet so don't expect to find a full 'how to do it' plan, but I'm getting there. Shots from the archive. Sunday, 13 January 2008. A Homemade jet engine (The journey begins). The 600 Watt vacuum cleaner that started it all. It's made in China, where they obviously haven't yet perfected the technique of making poor quality goods that hold together just long enough for you to lose the guarantee. Bottom left,...

Jet Turbine Engine: March 2008

http://jetturbine.blogspot.com/2008_03_01_archive.html

This is an ongoing record of my struggles to make a functioning jet engine from scratch. It isn't done yet so don't expect to find a full 'how to do it' plan, but I'm getting there. Shots from the archive. Thursday, 20 March 2008. After getting some advice, I decided to remake the Combustion Chamber. The old one wasn't working properly, the gas mixture appeared too rich, with yellow flames visible at times. So I made this one, with much smaller air-holes. Anyway, it seems to work.
