Next you know, we will get asked a question about how to design plane wings.

I know someone who can do that for you providing you need wings for fighters or UAV's and not commercial aircraft.

Got it !!!

I've injected some pine resin from scotland, works a treat now !!

Amazing how much crap comes out with it

The nhv is an aerospace term as in validated high pressure shaft speed or is it used elsewhere.

Have you tried reversing the polarity?

She canna take anymore.....

I'm currently development testing a water ingestion function in a gas turbine engine and I can't drive the T30 signal low enough to trigger it. Even though I'm at sub idle and NHv has gone through the roof. Could any esteemed member of this board help.

I presume that you are injecting water to increase thrust. You will need a water ethanol mix and a fine injector. I presume you have made the gas turbine with a couple of old car turbochargers.

My guess is the you are tying to trigger a digital sensor with an analogue signal. You will need a D/A converter

You're one of my esteemed customers, aren't you?

Eh ?

either attach an attenuator to the T30 line, or try running the turbine hot and dry. You could also try replacing the feedback line with a false reading i.e. attach a watch battery or some such

Who's that northern bird on here - someone said she had a cockatoo

[Drewster]

Good work people.

My PM is happy that we can save money by doing the water and bird ingestion tests at the same.

Does anyone know of a 'Bird' who may volunteer to get in the pool.

NOB25 - apparently he has got a little budgie

I suggest you run a cable up to the top of the old clock tower. That should generate enough power should it get hit by lightning. If anyone asks, just say it's a weather experiment.

It worked for me when I was in a pickle once.

Is that enough to generate 1.21 jiggawatts?

[conned tractor]

Thanks for the replies , tried them all but none of them worked.

We're going to take the engine to the local swimming pool and see if we can get it to suck some water up. Some of us may have to get in the pool. Any suggestions on suitable attire ?

Chicken suit, so you can carry out the bird ingestion test at the same time.

Try the local duckpond instead - they are usually only a foot deep.

If it's powerful enough you can try a bird ingestion test at the same time...
