In those funky 1950's, they took a turboprop Vickers Viscount and mounted two Rolls Royce Tay engines instead of the four piston engines. I assume this was a convenient way to test those jet engines. Was there any intention of actually producing this variant? How fast/cruising speed of this airliner mutation? Were any airlines interested in buying them? Could the propliner airframe and components take the higher altitudes, temperature and pressure differentials of pure jet flying? Drag and efficiency, fixed wings with jet engines practical or not? Was there any other commercial prop airliners that were mounted with pure jet engines?

Hey Zippyjet.

The Viscount was a turboprop with RR Dart motors

It is amazing how simular this jet version is to the Avro Canada c.102.

The aircraft that should have been the first jet airliner.

Britian withheld the engines until they guarenteed the Comet would fly first.



OBAMA-WORST PRESIDENT EVER....Even SKOORB would be better.

Actually the Viscount was built with two prototypes, the first called the Model 630 flew on July 16, 1948, and the second prototype was built as a test-bed with two the Tays instead of the Darts. The first prototype was awarded a restricted Certificate of Airworthiness on September 15th 1949 and full certification was awarded on July 27th 1950. The jet engined version was not pursued any further.

This was also the time when realization was dawning upon aircraft designers that aircraft with jet engines had entirely different design needs than prop driven ones. Hence the idea of simply replacing the prop with a pure jet without significantly changing the design to incorporate structural modifications just dropped away.

Somewhat strange that the idea reincarnated with the Dornier 328 turboprop and jet versions but met a similar fate.

Piston engines? What piston engines?  Confused

Not to worry, there were still plenty of them flying for those well heeld enough to take to the sky. DC 3's were still a mainstay, the DC 6 and 7 were the hot ticket and who could forget the Conny in her heyday. The super G was still several years away. Back then, everyone thought Communists hid under their beds and even saying or thinking preggers on the TV could land you in jail working the chain gang detail.  Big thumbs up

No pistons on a Viscount, only turbines. They are actually jets that are turned by propeller blades instead of fans. Now a Cirrus SR-22, that is a piston
