What was the fastest piston-engined plane by the end of 1947 which was produced by an aircraft company? How fast in level flight?

Mustang 650mph?

 

[Sidewinder]

Could be the Dornier 335 V1 (hows that for obscurity) 775 km/h

Before I go down to the library to check the reference books...
What are the prizes, Rail?

tx: A ball of wool for Mrs H to knit another jumper...

Graham: It isn't a mustang. The highest speed I could find for any Mustang was their final variant, the P51-H clocked at 487 MPH
(See http://home.insightbb.com/~p51h/p51h.htm)

Richard: Nope, not that either, though the speed isn't that far off...

Not a prototype Xzylon is it Jeff?

or Supermarine Spitfire?

Commonwealth Aircraft Corporation's CA-15 at 502 mph or 803 km/h.

Prototype flew before 1947 but speed was set in 1948 by the same aircraft.
Level flight speed average = 448 mph fully armed.

A first post - welcome to the forum bump

I should just mention that you have to be rather careful with your choice of language around here though - terms like "fully armed" can invite a whole barage of jumper and general knitwear jokes. Forewarned is fourarmed as they say.

Anyway, I don't think anyone's mentioned the Thunderbolt yet so I'll plump for the ol' P-47???

I think the De Havilland Hornet could be the fastest. It was basically a smaller version of the mosquito... It never saw active service though. I dont have the stats yet though.

For my birthday, I had a great book on the history of the Spitfire, this is a clue,
no it's not a Spitfire.

Hawker Fury ?

 

[goldfish_samurai]

Hawker Typhoon? Maybe a Sea Fury?

 

[bump]

"level flight" at which altitude please? You will have different "fastest" at different heights depending on engine variables, prop pitch etc.

 

[Guest]

Hi Bump,
Sorry it does not give altitude. I agree with you it should and it's nice to see another member who likes planes.

[bump]

At low altitude, CA-15 is a good candidate. For high altitude, an interceptor designed to combat US B29 fleets, Kyushu Shinden, at 466mph at 28000 feet. Both aircraft never saw active service and as prototypes with limited air-time, stats are variable according to sources.

 

[goldfish_samurai]

Ok guys, I have the stats for the Hornet - The Two 2030 hp Rolls-Royce Merlin engines provided a top speed of 472 mph. It first flew in 1944.

Grumman F8F Bearcat 528.33 mph
(849.55 km/h) 21 August 1989

The plane was built by Supermarine.

jeff if your refering to the supermarine seaplane which won the scnieder trophy check the above link

 

[goldfish_samurai]

All I can think of is the S6 ? It was the fastest once, but it was slow compared to the speeds achieved by 1947.
