This aircraft was produced in numbers and certainly saw Squadron service.

Lightning Mate 6th Mar 2012 15:32

French....?

MReyn24050 6th Mar 2012 15:48

This one was not from France.

Evening Mel.

Quick punt...the North American Savage? Can't find any decent rear shots of it, must have been a shy creature. :)

(Yes Mel - unfortunately I typed Boeing XF7B-1 :( )

MReyn24050 6th Mar 2012 22:59

Well Graeme for a quick punt, it was a very good punt as it is the North American Savage AJ-1

The date of its design inception was a time (late 1940s) where the US Navy was faced with procuring the nascent jet engine, while still having to rely upon the simple yet well proven reciprocating engine. Jets at this time were unreliable and used large quantities of fuel; however, once they were developed, they produced performance that no piston engine could ever provide. A compromise was made to include in the Savage two Pratt & Whitney R-2800 piston engines, with a large turbocharger fitted inside each engine nacelle. This combination made it possible for the R-2800 engines to produce rated power (2,500 hp/1,864 kW) up to 42,000 ft (12,802 m) altitude. An Allison J33 turbojet was fitted in the rear fuselage. Interestingly, both engine types used the same fuel. The piston-turbojet arrangement was intended to give added power on take-off and extra dash speed while in combat. At high altitude, this "boxy" looking (but aerodynamically very clean) airplane was remarkably fast, reaching more than 460 mph (740 km/h), when the jets of that era were not very much faster.

You have control.

Thanks Mel. I'll only be on sporadically for the next week, so open house.

Lightning Mate 7th Mar 2012 13:54

Too long at OH...

How about the Northrop Snark?

How about the Northrop Snark?
Go back to search mode mate. :E

Kitbag 7th Mar 2012 20:02

The more I look the more closely it appears to resemble a turboprop intake.

Lightning Mate 8th Mar 2012 07:18

Not a turboprop mate.

With the lack of "warning jet intake" and the fact it is not a turbo prop, could this simply be a piston engine? Secondly, the trim markings look simply 'civilian'. Lastly. Is that a landing gear I spy in the back ground and if so, does it suggest more than one engine?! Hope I haven't tried to winkle too many clues!

Lightning Mate 8th Mar 2012 10:38

It's a jet engine trucky.

Not strictly military, and yes, you do see part of the landing gear.

Wannanuther clue?

trucky04 8th Mar 2012 13:17

With the square shape intake it suggests under wing mounted? Also, was this primarily civilian/biz jet with the exception of a few going to the likes of coast guard etc?

Lightning Mate 8th Mar 2012 13:20

The intake is under the front fuselage.

Not a civilian/biz jet - not coast guard.

Try NASA. ;)

MReyn24050 8th Mar 2012 13:36

NASA Dryden's F-16XL-1 perhaps?

Lightning Mate 8th Mar 2012 13:39

Sorry Mel but no.

Would you like another clue in view of your generous one on What Cockpit?

MReyn24050 8th Mar 2012 13:50

NASA Himat perhaps. I gave the generous clue on Cockpit because it was dragging on a bit and it was going to be a case of attrition for every Heinkel produced pre WWII.

trucky04 8th Mar 2012 13:54

Its the NASA experimental HiMAT aircraft. OPEN HOUSE if correct

trucky04 8th Mar 2012 13:55

I should F5 more often!!!
