1978 Harrier T.4 road test.........
 

Hi,

I found this December 1978 Autocar 'AutoTest' on the Harrier T.4 'a nippy two seater for the sportsman'......... thought some might enjoy seeing this and remembering those times........

Anyone know which 233 OCU T.4 (Y) is in the photos?

cheers,

I can't recall seeing that the first time around, so thanks for posting it!
:D

Having checked the date I am reminded that, in the old days, the magazine did these jokey road tests in the Christmas edition. ISTR a test of the vehicle that carried the Space Shuttle from the Assembly Building to the Launch Pad, among others. Thanks for posting!

Seem to think it may have been XW934. God I feel Old!!!!

Interesting to see it cost £5 million. How much is the F-35 going to cost us, again?

Thats £25million, inflation adjusted.

291 Litres/100k...sounds like my Discovery. :(

Any truth the rumour they trialed Motor diesel in the Pegasus as a contingency if all our bases in Germany had been shwacked, with a view that the jet could be gassed up using fuel from a petrol forecourt?

Probably utter hoop, but seeing as Diesel is similar to Kerosene, may be an iota of truth in it....

I see no reason why standard diesel fuel could not be used the Diamond DA42 is certified for use with both Jet A-1 and standard diesel motor fuel as it is more or less the same thing.

Having done the manufactures maintainence course on the engine I was told that Jet A-1 has far less lubricating qualitys and so the challenge was to get a Diesel engine fuel control system to run reliably on Jet A-1, this is a problem you would not have in reverse.

Added to this the life expectancy of a Harrier in a pan European conflict would probably render long term reliability a non issue.

IIRC, the pegasus could run on diesel for 10 hours (low level - as no anti-icing additives). With WW3 life expectancy at the traditional 20 minutes, it was not thought to be a problem.
