H S Trident

The Trident was an excellent design and a lost opportunity. The original design by DH was considerably larger and the three jet layout was novel. As many other civil projects, government support was dictated by perceived suitability for the national carriers, BOAC and BEA. It was decided that the design was too large for BEA, the perceived launch customer and the project had to be down-sized. As it a result it wasn't considered suitable by most other airlines and sales were restricted by that. Within a year or so Boeing launched the 727, almost a clone of what the Trident was originally intended to be. That became one of the biggest selling airliners of all time. Very frustrating.

Advert


the boeing company was invited to come and take a look at the trident when it was under development.

and guess what.

yup we gave them all our designs and technical developments for free, Boeing said thank you and used them to develop the 727.

yay we kicked ourselves in the butt once again.

Very nice. Piers - I recall them being called the 'de Havilland Ground Gripper' too !

I believe it was one of the very few aircraft certified for selection of reverse thrust in the air. On approach to Dyce after they selected reverse thrust on short finals to 36 there was no 'go around' option after that, which is partially why one ended up slightly over-running onto the grass.

A very solid and well engineered piece of kit. Pity BEA's insistence meant it was smaller than first planned.

so a vc10 at the same scale as the hs trident would have a 70" span.

hmmmmmmm.

that would mean removable wings and retracts and weight and complications.

maybe 35th scale as that would give me a wingspan of 50" only very slightly larger than the trident.

fixed wing,twin pusher props, no retracts, hand launch, lighter and less complicated.

more hmmmmm
