Two quick questions about jet engines.

1. whats the cheapest cost for a jet engine?

2. whats the cheapest cost for a jet engine capable of going mach 1?

if anyone knows please post, im trying to develop a cheap fighter for export.

Thanks!

Its not really just the engine that counts for going Mach #. Its a variety of factors, thrust to weight ratio of aircraft (where the engine comes in) along with general aerodynamics of aircraft, drag, etc.
With a really sleek light jet you can get by with a lower thrust engine, but for something heavier and/or less aerodynamic, you'll need a higher thrust engine.

Sorry I can't help you with cost other than saying this...if you build it cost will be determined by constuction method.....if you use cheap labour & parts then it's going to be cheaper than if you built it with the best parts & high quality labour (robots are cheaper than humans in this, but have a higher start up cost).

Heres a useful bit of trivia..the germans made a working jet aircraft before world war 2 :shock:

Well im looking to create a light short range interceptor fighter that only has cannons. Its basically only going to be good at going after bombers. And I want to keep the cost below 5 million dollars. Is that possible?

Have a look at the Mig 15, 17 or Sabre which were super-sonic.
These were post-WWII and in the Korean war era.

I saw that on TV last week. The only reason it wasnt availible on combat aircraft at the beginning of the war was Hitler kept changing his mind about whether it should be a fighter or bomber until it was too late.

Price for engines: http://www.safetycenter.navy.mil/aviation/maintenance/enginecostdata.htm . Most notably that the F-414-GE-400 for the F/A-18E/F is only about $4.3 million (for each).

For the F-16C light fighter however, I'd guess that it is similar, but I can't find info about it since I can't find a reliable (aka USAF) site about engine costs (that was navy).

What about something like the Alpha jet which is a trainer?
Small and capable of carrying cannons with some bomb/missile capability.

Ya it's the program I saw too....just imagine what the world would of been like if Hiter was sane & stuck to the fighter design. The ME212 was a superior anti-bomber aircraft up until the allies learned how to combat them, if the germans had it before the allies developed mustangs & invaded europe :shock:

do you have a link to the specs to that?

We would be goose stepping right now.

It's only about Mach 0.8, but you can probably go fiddle with the design.

Nah, being the 2nd Anti-Christ. Hitler was fated to fail and die.

thanks.

Belem have you seen the docomentry on the breaking of the sound barrier by the X-1? (I think it was called that) that will give you a hint on breaking the sound barrier.

I saw bits and pieces of that. I fell asleep during it actually.

These were post-WWII and in the Korean war era.Those three jets are only Mach capable in a dive. Otherwise they all had speeds under Mach during level flight.

True. The Mustang (modified) could do the same I think.

I heard there was an experimental Mustang with a turbojet engine instead of it's normal engine...

Not the Mustang with a turbo-prop either.

My nation developed and uses this engine in a few planes:

TF525-420 9 500lbs thrust turbofan engine

It weighs 900lbs and has low maintainence costs. Unfortunately IC we would never sell it to Belem.

Fast factoid, because I friggin feel like it: The P-38 was the first American fighter to experience compressibility problems.
