Classic British Flight Sim

Hi all,

What type of thrust reversers did the Super VC10 have and how did it work? One of my friends asked it recently and I couldn't give an exact answer.

Thanks,
Gergely

Hi Gergely

If you hang around for a while I'm sure that Tonks will pass by soon and give you the answer. That is if he isn't jetting off to some exotic location!!

Regards Nigel.

The reversers on a VC 10 are internal unlike the buckets you see on some engines

Internal doors drop down into the exhaust flow deflecting the thrust upwards and downward through the apertures in the top and bottom of the engines opened up by the doors opening up and blocking the exhaust flow.

The thrust hitting the doors causes a backwards force.

Sorry not very technical and a bit more complex.....but maybe this will do for now.

Originally the Supers VC 10 had reversers on all four but later two were removed.

The reverser exits are the dark grills visible on the top and bottom of the engines on the VC 10 and the BAC One-Eleven.

These pics might help a bit


This is the same RR Conway engine as the VC10 but mounted on a 707-400. You can see the clamshell doors and the hinge that holds them in place in the jetpipe.


Here on a 1-11, you can see the doors are closed so the gasses pass through the grilles and are deflected forwards.

Hope this helps

As far as I know the reversers on a 707 work completely different to the VC 10:think:

Read again - he's referring to a Conway-powered 707... the 707-420 if my memory serves.

The cascade type reverser is the one most often used on underwing-mounted turbofan engines these days, and it was still quite innovative when fitted to the VC10. The only external visible sign would have been exhaust efflux venting through the cascades, althoughif you stood behind the back of the engine (wearing asbsestos knickers and sunblock) you might have seen the internal buckets move to close off part of the nozzle.

Generally, and again IIRCm, the cascade type uses bypass air rather than heated core, so is easier on surrounding paint and finishes, and doesn't melt the tarmac.

I think the system is called Cold Stream Thrust Reverse.

Hi,

Thanks for all the answers!

Why is the darker shaded area not deflected forwards? Was it an attempt at VTOL?

Helps to keep the nose on the deck
