How come no swept wings on a prop plane?

Re: How come no swept wings on a prop plane?

also remember seeing an unpainted airplane doing some fly-bys. It looked like an unusual Mustang. I can remember the announcer saying that it had Lear Jet wings and was being built for racing at Reno.

It was my second year that the Air Races when I was there in the grandstands right in line with the home pylon for it's final flight. It still makes me sad.

Bill told me that flight at Arlington was when Skip decided that the airplane went REALLY fast downhill! So fast, he managed to tear off a gear door in the process... do you remember seeing her missing a gear door??

Technically all wings have sweep. It's just some wings have a sweep of 0. Positive sweep is backwards, negative sweep is forwards.
Sweep is the angle of the quarter chord line to the spanwise axis. So even though a P-51 has angled leading and trailing edges the sweep is still zero.

Other simple explanations on swept wings

and forward swept wings

Cornell racer is a modified Buckey so still a straight wing.

I was at Arlington that year and saw the door come off, or rather just after it came off. I used to work at AWO and got to see most of the shows in the 90s from the east end of the field. I remember it was during an impressively fast pass by Skip, seemed lots faster than the previous ones. Looked like the gear door came off just about show center, my friends and I watched it work its way to the ground after Skip passed. We had no access to announcers or radio so I don't know if anything was said about it at the time. Later on I was told that it was indeed one of the strut-mounted doors.

Honestly, it was so long ago that I don't remember that detail. I'm pretty observant, so it's possible that I noticed it at the time.

Sorry my lack of proper terminology, swept or not swept ?????? I'm talking what does it take to have the plane controllable at mach speed? And the link proves that propellers will do mach speeds despite all the nay saying. I guess I have a problem when someone says it can't be done. I like to find a way that it can be. If I remember a P51 could almost cruise at altitude along side a jet airliner, well maybe not cruise but?

Re: How come no swept wings on a prop plane?

Interesting topic. Just WHAT constitutes a swept wing? If you look at a DC-3 or a B-36 (to mention a few) they have swept LEADING edge, but I'd hardly call that a swept wing. Bell experimented with a swept wing on a P-63.
Always thought Vendetta and Miss Ashley II looked really good and thought they had a lot of potential, but if it was so good......why didn't anyone else follow that pattern? Way back, Miller's Pushy Cat had a swept wing in F1.

Enjoying this discussion.

It's a bit ironic - at least to me - that the P-63 with the swept wing was known as the L-39; the L-39s we know are straight wing jets:
