Hi,

Not much to do today, it was blowing very strongly, and it kept raining, so I thought I would put a few more decals on the heli.

Comments welcome of course, good or bad.

G-SWSM , It is not a Gas Turbine, it is a jet turbine, one of the reasons your exhaust point sideways

oh,

But after reading around I have come across these two threads and details, one of which is from Sara at Wren.
If you are wanting to build a turbine engine we have two alternatives for you. For the homebuilder who has a workshop with lathe, milling machine etc. it is possible to buy the plans for our MW54 Mk 1 and build either a thrust (jet) engine or a gas-generator (heli first stage) engine. If you don't have a home workshop it is possible to buy the MW54 Mk 3 kit as either a thrust engine or a gas-generator.

Sara Parish
Wren Turbines
Then this one,
there are two types of turbine. The plank type are designed for thrust and squash the exhaust gases into a "jet" stream and is therefore more refered to as a jet . The other type of turbine is a "gas generator", this is designed in such a way that the exhaust gases are slowed down and allowed to expand, thus rotating a second stage wheel connected to a gearbox, this is better know as a two stage Gas Turbine.
So I am somewhat confused now Peter.

G-SWSM , Stay confused, Your PHT3 turbine, was designed as a jet unit,it ws then coupled to single stage (belts and pulleys)mechanics for use in Helicopters, still a thrust turbine
JetCat like Wren then developed a gas turbine and coupled it with a second stage unit (no direct link to the gearbox)
Although useing the same turbine unit, it can be, jet or gas, simply by changing the design of the turbine wheel within the turbine

Either way, it's a killer paint job you've done there

Stay confused
No Problem Peter, I can certainly manage that.

Thanks for the compliment Paul, glad you like it.

Hiya,

Very nice heli, is that a robbe conversion? Do you have any pics of the mechanics?

Thanks!

Hmm, that vac on the wall needs a rotor too. Nice paint scheme. LOL.

The beatings will continue until morale improves...
