I am looking for a Spitefire that had a pair of counter-rotating props. It might have been a Naval version and I am not sure of it name to google it. Also the Wyrens had a counter rotating prop with a jet engine? I am lookiing to do a 1/72 scale model if I can find out which one it is.

Hi Jim.
Your thinking of the Supermarine Spiteful.
WIKIPEDIA ENTRY
The Wyverns had a counter rotating prop, but a propeller driven jet engine?,,,think about that?

Hi Jim

The Seafire Mk. 47 had contra-rotating props - is that the version you mean?

All the best

Yeah like helicopters, A turbo prop?

I agree with Lampie, think about it.

I use to teach Airmanship (Aircraft recognition) to the Air Cadets over here in the UK and one of the first things they were ever taught is that helicopters have turbo shafts (as the shaft goes vertical) and aircraft have turbo props (as the prop is on a horizontal plain) eg a Tuccano or a Jetstream. If a jet engine is involved then it would be a turbofan or turbo jet.

Hope this helps

Some Spitfire Mk XIV, Mk 21 and MK 22 were fitted with contra-rotating props.
Also Seafire Mk 45 and MK 47.
The Seafang had a contra-rotating prop but not the Spiteful.

OK! How many cylinders did the Westland Wyvern use? Also what is the power plant for the C-130?

Not sure what this has to do with 'Spitefires' but:

The Westland Wyvren used the Rolls-Royce Eagle 24-cylinder H-block piston engine. Also an unflown pre-production aircraft, fitted with the original Eagle piston engine, (serial number VR137) is on display at the Fleet Air Arm Museum in Yeovilton, England.

The initial production model, the C-130A, was powered by Allison T56-A-9 turboprops with three-blade propellers. Deliveries began in December 1956, continuing until the introduction of the C-130B model in 1959. Some A models were re-designated C-130D after being equipped with skis. The newer C-130B had ailerons with increased boost — 3,000 versus 2,050 lbf/in² (21 versus 14 MPa) — as well as uprated engines and four-bladed propellers that were standard until the "J" model's introduction.

The "J" had new Rolls-Royce AE 2100 turboprops with six-bladed composite scimitar propellers, digital avionics (including Head-Up Displays (HUDs) for each pilot), reduced crew requirements (2 pilots — no navigator or flight engineer), increased reliability and up to 27% lower operating costs. The C-130J is available in a standard-length or stretched -30 variant

Wow... Sam's on a roll tonight

I knew there was a reason I fell for her

I also found out that the Westland Wyvrens were designed to use a turboprop engine, but the final design was dropped or cancelled. The huge exhaust on the Wyvrens looks like the jet exhaust on a truboprop.

Only the prototype Wyvern was powered by a piston engine. Production Wyverns were powered by Armstrong Siddeley Python turboprop.

Trumpeter does a Wyvern in 1/72 scale.

Czechmaster (CMR) does a Seafire 47 is 1/72 but it's resin and a bit pricey.

Supposedly Special Hobby will be doing one too ("future release").

Sorry, I thought with being asked how many cylinders they had I thought we were going on about the prototype The Trumpeter kit is a very nice kit both the 1/72 and 1/48.

So, lets see if I have my power plants correct. There are recipricating engines with pistons most likely gasoline, Could be rotary or Wankel engines, also rocket, ie ME163, or ramjet engines ie V-1. And then there is an engine with lots of blades that compress the air mix it with fuel and when they burn are blown out the back , jet engines. Correct?

Jet engines' exhaust turn some more blades that turn the compressor section's blades to keep it running. Correct? Now if the exhaust blades shaft turn a propeller instead it is a turboprop. Correct?

What does a turofan engine do that is different that the straight jet and the turboprop?

[quote]Not sure what this has to do with 'Spitefires' but:

When you first look at them Spitefires, Seafangs and the others look alike, since they came from the same family. The Westland Wyvern looked like a newer member and did have the counter rotating props like the last Spitefires.

You have to start some where.

After a quick Wikipedia search this may help with your queries:

Turbofan
Turboprop
Turboshaft

Jet Engine
Ramjet

Piston Engine
Rotary or Radial Engine
Wankel Engine

Hope these help

Cheers
