Its probably not a fake, I've seen at least 4 'wet' harriers which will do near or full VTOL. I've even designed one myself, but with an OS-90 VRDF, tuned pipe and Viojett with 20% nitro fuel pumping out 4.5 BHP at 26,000 rpm it was a bit noisy at 100 dB+.

Its also only about 60% efficient after you turn the airflow through 90 degrees through the nozzles. I've seen a prototype which was in Jet international which was flown before being 'given' to Yellow aircraft for final testing. This was a year or so ago (Eric Dainty's harrier???). This might be it, dunno.

It can be done.......

As for an electric version, well........

I've tested the power setup and am into final build, another few months and I'm hovering.........Oh yea......

Suspicious

No pics of the model, no development story, no pics of the tooling, and a reference to the need for funding make me very suspicious that this venture will ever get off the ground. Even if it does get to the production stage it looks to be an expensive ducted fan in a turbine world.

I was noticing the same thing ... both sites actually. The Harrier site has nothing to offer at all and the X-35 site has some great photos of the real plane but nothing on the model.

Is this what is called in the computer industry "vaporware" or do these guys think they are working on black projects at the SkunkWorks?

I'd say they were vapourware.

If they had a working model there would at least be a picture of it, even if they wanted to keep the tech. details secret.

My club hosted a fly-in for the GTBA (Gas Turbine Builders Association) last year and a local guy called Mick Koskela flew his .91 d/f Harrier there. He's been working on this for about 15 years so far, and finally has a model that will hover or fly forwards ... but can't do the transition.

Here's a pic.

Details & more pictures here:

Vapourware................


X35b....................

Wait 2 months then eat my shorts......................

Seriously though I am aware that some (maybe all of you guys out there) think that I'm all talk and no action. What can I say other than this is a very hard task to achieve and I've been at it now for about 2 years planning, procuring parts and testing various ideas (and planes, remember the X32b?). So if you dont believe me then thats fine....just remember what you said when you see my plane on the cover of RC Jet International. Nuff said.

I am suspicious about the Harrier though, and I'm NOT asking for money to fund my project, if you looked at all the pages on my site you would see that the expensive bits have been procured (3 x HP 220/30 a4 s p4 brushless motors, 3 x Shultz 35bo ESC's, 3 x Wemotec HW620 fans, 3 x Pizo gyros, 24 x 2400mAh cells matched and zapped, spring air 600 series retracts and various other bits and pieces).

As for the fact that there are no pictures, well there will be no pictures untill it hovers and the hover will be validated this summer by Chris Golds and Gordon Whitehead (Jet International and EFI columnists who happen to live close to me, thas assuming they want to see it, and I cannot think why not)


I'm not asking anybody for money for research or tooling or equipment its more a personal quest to do the electric VTOL thing. I may yet fail but its beter to try and fail than to never try at all.

You started it by saying the X35b was vapourware.....;D

Why not post a few construction/installation pictures?

Allen,

Nice try with the bait for the photos, I took the lure but spat it out (it nearly worked!!).....

Love the YF23........

I do recall seeing the now defunct X 32 framework, or flying stick last year maybe. I know Doc trashed that whole thing for the X 35 some people are just scale nuts,,,, what can you say.
Oh, Allen, if you really want to rattle Doc, post the construction of you VTOL EDF,,,,, that elll shake em into production .

Helium Ballon Shaped like a Harrier?

Maybe we are just thinking too much inside the box here!! A puffy indoor ballon sort of shaped like a Harrier and powered with tiny electric motors (a la Peck Polymers R/C Blimp) could conceivably fly for the 20 to 30 minutes purported and be built in 24 hours. You could sort of say that by taking off vertical and then going forward you could maybe simulate the Harrier's flight regime.

No offense to you Doc. We all know that your heavier-than-air X35 JSF is a serious engineering project. You have already proven that to us Ezoners with many progress pictures of tilt mechanisms, hardware, used appropriate Model Airplane buzzwords, etc.

In the deserts of Southern CA we have some really big "dust devils" where lawn chairs have been known to takeoff and fly for 20 minutes. Perhaps this is how the Harrier purveyor intends to accomplish such a feat with a heavier-than-air model ?

Damn, there goes my B.S. Meter again.


Does anyone remember a VTOL that was in MAN 5 or 6 years ago? It was wet powered, mid engined. A worm drive turned the engine/prop through 90 degrees. I know, it's not a scale harrier, but I'm curious if this type of setup would be possible with an electric powerplant.
