Title: C-130, Pegasus vectored thrust engined *finished + more pictures*
Post by: sandiego89 on March 10, 2019, 12:44:52 pm
Near the height of the Cold War numerous V/STOL projects were undertaken to allow dispersed aircraft operations at remote airstrips, roadways and other hide sites.  It was reasoned that fixed airbases in Europe would be early targets in any Warsaw Pact offensive, but V/STOL fighters and attack aircraft could disperse to remote sites.  The Germans recognized that transport aircraft could also be beneficial for such remote operations and developed the Dornier Do-31 which used lift jets and an early versions of the Pegasus vectored thrust engine for V/STOL flight.  The RAF, not to be outdone by the Germans, and recognizing that the Harrier would require a bit more support than a "ladder, toolbox and a fuel bowser" suggested in some literature, desired a large aircraft to carry fuel, munitions and other supplies directly to the Harrier support sites. The US also became interested with their pending Harrier AV-8A program...   

The plan: C-130 with 4 vectored thrust Pegasus engines, and other modifications.

The Kit: Airfix C-130E, 1/72

A different approach to a V/STOVL transport:
Bristol 208 concept, four Pegasus in two nacelles.
Bristol 224 concept, two Pegasus and 8 lift engines.

You'd need quite few.

This was on the SIG stand at the Perth (Scotland) show about 6/7 years ago.
I can not remember who the builder was.

More blended like the Do31, not nearly the pylon on the example that Jaybee posted- I had not seen that before- was hoping one had not been done, but I found that is pretty rare in whiffery world. 

I also adjusted the title a bit, for you old antique radial head thinkers!

I think the distinction needs to be made between;

the Bristol Pegasus;

and the Rolls Royce Pegasus;
(https://upload.wikimedia.org/wikipedia/commons/thumb/d/da/Rolls_Royce_Pegasus.JPG/2560px-Rolls_Royce_Pegasus.JPG)

due to their power outputs being slightly dissimilar.

Engine work has commenced. 

I will cast 4 resin vectored thrust Pegasus engines using the mid body of a Harrier.  Sadly a Harrier has been sacrificed- chopped of the wings, nose and tail. Repositioned the side intakes to form a single intake 

Here is the master primed. Decided to keep the heat shields, nacelle design pends...

(https://imagizer.imageshack.com/v2/800x600q90/922/nqeRYY.jpg)

Made a 2 part master mold.

Two Harriers got sacrificed for this project, I used some airliner engine fronts of a different scale which worked out to be the right diameter

Very interesting  :thumbsup:

Seeing the plaster mould takes me back. We used to use plaster to make the moulds from which to cast white metal figures back in the day. You had to make sure the plaster had thoroughly dried out though or it got a tad exciting  :wacko: Then resin came along and I haven't seen plaster moulds since, certainly not seen resin being cast in plaster. Really interested to see how this turns out. Good luck  :thumbsup:

I suspect the mould's life will be significantly shorter than a comparable rubber one, from my experience in using both.

The mold is rubber. Specifically Alumilite RTV Silicone. Just looks like plaster due to the color.  Made it two part, as it would likely be impossible to get the shape out of a single piece mold. I have never made a plaster mold.  I have only made a few RTV molds before.

Thanks everyone! first time I have molded a complex shape. 

Making the master for the rear of the nacelle.  Was unsure how to best mount the engines, directly underneath the wing or more towards the front in place of the turboprops, but to maintain center of lift/center of thrust/center of gravity considerations to allow super STOL, a podded engine, with barely a pylon seems to work.

Harrier GR3 providing the rear of the nacelle.  Putty and bondo.

Meanwhile, the early RAF tan had to go.  Primer on.

When I was working out where the engines would go on my STOVL Canberra, I figured that when the nozzles are swiveled downwards for vertical take-off, the center of the four nozzles* should be in line with the load cg on the aircraft.

* the center being where two lines cross, one line running from front-right nozzle to rear-left, the other line running from front-left to rear-right.

Thanks kitnut, I had the same thoughts with the center of thrust needing to go through the center of gravity. I am toying with mounting the outer engines a bit further back to give a wider spacing for the 16! Nozzles, but that may look odd. Pitch control will need to be robust...

Wow.  That's great work.  I love the resin casting aspect of it.  In my experience you've probably hit the sweet spot in terms of the size.  I've tried very small moulds and they're a real pain to work with, but something this size should work very well indeed.  I'm loving where this is going.

Do the "cold" (front) nozzles produce the same thrust as the "hot" (rear) ones?

I reckon they must do, in lbs thrust anyway, 'cos the Harrier's nozzles are positioned an equal distance apart from the CG.

I've read somewhere (can't remember where though) that they do on the Harrier. I might have asked someone who was in the know too --- but it worked out very well for my project because a lot of things suddenly started to fall in place technically with the build after I discovered that.

Back at it, was out of town for a week and had to reorder a new batch of two part resin.  New resin is white when cured. 

Made a mold for the aft part of the engine nacelles. 

As the resin set put a small screw into the resin to help pull the nacelle out of the mold.  Helped a lot.

I think super STOL.  I have been wrapping my head around VTOL, center of thrust, center of gravity, trim, etc. and just can't imagine a workable VTOL.  I put the engines a little far forward, perhaps too far, but they look great there, and preserves the original wing mount.

This model is inspired! I'd not been into this GB and I'm wishing I'd gotten here sooner. Those engine pods are gorgeous!

Making it STOL is prolly a good idea.  Imagine the amount of dust raised in a vertical take off from an unsealed strip...
 :o

It's looking very promising. :thumbsup:

Do you think it could land in and take off from a football stadium? One in Tehran perhaps?

Thinking about some puffers to help with pitch control

Puffers are only necessary if you're going VTOL.   As the engines are mounted rather forward of the C-of-G, I think the load would be rather limited in the VTOL condition.  I'd stick with STOL instead.  No need for puffers then and your engines are fine where they are.

United States Marine Corps VC-130H at Cherry Point, North Carolina 1978. 

"Sweet 6" pictured at her home base of Cherry Point.  The VC-130's had been primary used to support AV-8A operations at austere bases, much like her RAF counterparts supporting Gr1 and Gr3 operations in Germany. "Sweet 6" was to later gain her place in history during operation Eagle Claw to rescue the American Hostages from the embassy compound in Teheran, Iran. 

The kit: 1/72 Airfix.  Self casted resin Pegasus engines (x4).

Thank you everyone! Great kitnut, hope they like it over there on BTS. 

A few more pictures.  I may do some more staging, but busy days ahead for me as the deadline nears.  Also toying with the big external fuel tanks, but think that might get a bit interesting between two screaming Pegasus engines  :o  Perhaps further outboard like the KC-130 refueling pods....
