HC Deb 03 July 1967 vol 749 c189W
82. Mr. Onslow

asked the Minister of Technology what proportion of the total research and development expenditure on the Olympus 593 engine for the Concord is attributable to the TSR2 programme.

Mr. Stonehouse

The design of the Concord engine was facilitated in its early stages by the experience gained in designing the TSR2 engine from which it was originally derived. Since then the Concord engine has been further developed. It is not possible to quantify the value of the original design.
