Grumman D-71/G-71

[KJ_Lesnick]

How would the Grumman D-71/G-71 have compared to the later F9F-2/3 in the following based on known data

• Rate of turn
  
• Rate of climb
  
• Rate of roll
  

I assume the reason the D-71/G-71 wasn't selected because the FH was underway and they were heavily burdened with other projects at the time, but I could be wrong.

I am not familiar with this.

And specs?

Not seen that before. Quite attractive!

The D-71 looks like a jet based on a Bearcat, is that correct?

That can't be bad... the F8F rocked in it's day and this plane would have probably been in the air around the same time as the FH

I'd not heard of it before. Looks good though .

Simple, light and elegant: I think the intakes were a little small admittedly, but that could probably be fixed.

Yes was a new one for me as well.  Good looking, similar to a P-80, and much better looking than a few of the early US navy jets.

Plenty of WHIF potential.

In fact there wasn't such designation as D/G-71 at all. The project called Design 71 was one of the earlier Grumman studies for a Navy Jet. As one can see the nose section is in fact almost the same as of the later (and real) F9F-2/3/4/5.

Any thoughts on what engine is depicted in the cutaway?  Looks to be an axial engine, significantly skinnier than any of the Nene derived centrifugal flow engines.

I've got that Unicraft kit in the stash. Looks very simple build but there is still that perennial Unicraft "what the heck is this ?" part

Isn't that what powered the X-3? Note the word 'powered' here is used in it's widest possible sense.....

Indeed a bit anemic, especially in early non-afterburning versions.  Would hate to take a wave off right behind the boat.  Thrust seemed to improve with later marks.

Thanks joncarr.

New to me too. I'd venture that being a Grumman product it would probably have done what it says on the box. Seems to me a jet Bearcat much like the Attacker was a jet Spiteful/Seafang.

Elegant too .

[Captain Canada]

Yes...very nice shape to that one ! Would probably have tip tanks in service too
