Rolls Royce pioneered the turboprop with the Dart, which powered such classics as the Viscount, HS748 & F27 / FH227 as well as the Gulfstream I, YS11 and CV600 (and some obscure British military types - Fairey Gannet??????). Later followed the Tyne, with moderate success, mostly with military types such as the Transall C160 as well as the Belfast and CL44.
There are thousands of PWC PT6's & PW120 srs and Garrett TPE331's flying on King Airs, Twotters, Caravans, Embraers, PC12's, Dash 8's, ATR's, Metro's, homegrown ATP's & Jetstreams to name just a few. After pioneering the turboprop with the Dart, why did RR drop it and leave the market to PWC?? I know the Trent is now very successful, but is there not room for another turboprop manufacturer?? I suppose the crisis resulting from the RB211 crippled further development.
Does anyone know when the last Dart was made? I know Super 748's and F27's were made into the mid 80's.

Dont blame RR for the Dart on the YS-11, blame the Japanese.
They took an engine that was optimized for the smaller 40-50 seat F-27 frame, and stuck it on signifcantly larger and heavier 65 seater plane.

Rolls Royce in the 1960's & 70's seem to have decided to concentrate on military engines and large civil turbofans, thus withdrawing from the turboprop market. Most companys find it difficult to concentrate on every possible aspect of their business. In this decision they are no different to Boeing or Airbus who steer clear of small civil planes.
