Doug Taylor

It's all right for you 'eros, but at my level there's a lot to be said for 'inshallah' or "OK God, I have control" when working with this sort of optimistic technology.God bless Doug Taylor - RIP 2019, age 89. He was 831 Squadron AEO in 1961-62 and 'Flight Deck Engineer Officer' of the Vic, as the FAAOA story below relates.

Lt Cdr Douglas Taylor - The Ski Jump

Lt Cdr Doug Taylor RN, the inventor of the ski jump, was a former deck officer aboard HMS Victorious in the sixties who was seeking an alternative to the Steam Catapult after witnessing the failure of the cats due to excessive heat in the far east. The runners either side of the cat slots had expanded due to the heat and the alert fighters could not be launched, so Taylor ordered the fire hoses to be turned on the deck to cool it down. Realising an alternative system with no moving parts would be desirable, he worked on his thesis at Southampton University and came up with a paper he called 'The Runway in The Sky', published in 1973.

HMS Invincible, lead ship of the class was laid down in 73, and launched in 77, without a ski jump (added during the fitting out stage). The ski jump was an upward-curving ramp at the end of the Short Take-Off run which imparted a positive vertical velocity to the aircraft. As well as offering more payload, the ski jump enhances safety because the aircraft is going upwards as it leaves the end of the ramp, giving more time to eject in the event of a problem. Initially, 7 ramps were fitted to Invincible and Illustrious, and Hermes and Ark Royal got 12 ramps. Later Invincible and Illustrious were refitted with 12 ramps.

On 30 October 1980, the test pilot, Lt Cdr David Poole from Boscombe Down, flying XZ439 made the first Sea Harrier launch from a ski jump at sea, from HMS Invincible.

Thanks for that. Sounds to me as if a full fuel and weapons load could easily make it all pretty marginal.
On the subject of Harrier take-off performance, at Gioia del Colle in Aug 1995 (v.hot) we were filming Jaguars and Harriers on OP DELIBERATE FORCE for HQSTC. To catch the Jaguars getting airborne we had to position a long way down the runway. The Harriers were at about 500 by the time they went past!
