WHIFS found while Google-ing

[Captain Canada]

Is that ever ! Sky MG ! lol Or the TR.17

Whilst goggling Mohawks I found this.

Looks good but i'm not sure where the wheels would be.

[Dizzyfugu]

Now THAT is a cool idea... I just wonder where to tuck the landing gear, and how long it might have to be to allow nacelle rotation?

[Captain Canada]

Woah....that's about the coolest whif ever ! I'd love to build one.

I could see the gear in the nacelles. I'm sure it could have some kind of pivot for VTOL, yet also handle conventional as well as an angled engine mode for STOL. Easy enough for a plastic whif engineer anyway

Couple of very interesting ideas; especially like the Whirlwinds .

[PR19_Kit]

Have the main gear toward the wing tips and folding inwards, then there's no issue with the engine pods at all.

What Kit said but ditch the nose gear and go with a taildragger layout

[silverwindblade]

If it can VTOL, as it's now a tilt-rotor, why not just have retractable skids on the bottom of the belly instead? Why limit it to just wheeled undercarriage.

[Captain Canada]

I'd rather have the wheels for ground maneuverability. besides, it looks like it could do a pretty good conventional or STOL in that configuration.

[zenrat]

I was thinking you might want to keep the ability to take off conventionally.
But then i got to wondering, can an Osprey take off conventionally?  Or do the blades start to hit the ground before the tilt angle is sufficient to get forward motion?

I have not seen one ever, but from pics I've seen they can do forward takeoff's with the engines rotated what looks to be about 45 degrees.

The one I saw at Yuma doing a demo flight back in March 2012, taxied to the front of the crowd, then did a short run forward then took off. It's rotorprop was set more about 30 degrees than 45. I couldn't say what forward speed it got up to before the wheels left the ground though -- more interested in the aircraft to notice --    (seeing as it was the first time I'd seen one physically, let alone one flying) I'd imagine the huge amount of prop-wash over the wing helped it get into the air as quick as it did.

[Captain Canada]

No. The rotors would hit the ground. They can do the rolling takeoff as mentioned though.

The Mohawk looks like it could. Not designed to hover around and sling loads, so I'm sure the props would be significantly smaller in diameter.

[kitnut617]

No. The rotors would hit the ground.  

Yeah!    I would say --



Here's a good video of a short take off, although the props look like they are nearer 15 degrees (off vertical) here.

They won't even make it through the first rotation.  And at which point the old saw of "College Degree to cause it, High school diploma to fix it" kicks in
