The Handley Page HP.111 was the planned military version of a passenger and cargo aircraft of the also planned civilian passenger jet Handley Page HP.111C , which was based on the Handley Page Victor bomber .
history
The Handley Page HP.111 was a military cargo aircraft and the HP.111C was a planned civilian airliner version of the British bomber Handley Page Victor . This was in response to a 1952 call by the UK Department of Supply for a new aircraft that would be suitable for both military and long-range civilian missions. Civilian models of the Vickers Valiant and Avro Vulcan V bombers were also planned for the same order . The Vickers V-1000 won the competition, but ultimately none of these designs were completed.
With the development of the Handley Page Victor bomber, Handley Page took up the idea of a passenger plane based on the Victor, called the HP.97. This should have two continuous pressure hulls on top of each other so that the fuselage cross-section had a shape similar to an 8. The cockpit and a continuous passenger area were housed in the upper deck. The lower deck, where the cargo hold was located in front of the wing roots, should be accessible via a spiral staircase. On the lower deck behind the wing roots were the passenger toilets, galley, reclining seats for stewards, cloakroom and a lounge. Depending on the stage of development, the project had tanks on the wing tips or tanks under the wings (like the bomber).
Following a request from the British Ministry of Supply, the draft of the HP.97 was revised and presented as HP.111 in May 1958. The troop transport should be equipped with seats in the entire upper deck and the lower deck (behind the wing roots), which were mounted against the direction of flight. The lower deck was also suitable for freight transport, whereby the freight could also be deposited in flight through a rear gate. Some pictures of the HP.111 also show the HP.111 with an air refueling probe. The HP.111 was also offered for the civil market under the designation HP.111C. On the one hand, it was intended as a full freighter, without a rear loading ramp, but with large side cargo doors on the upper deck and the rear lower deck. On the other hand, the HP.111C was also offered as a passenger aircraft, but now only with the passenger compartment on the upper deck; the lower deck in front of and behind the wing roots was designed as a pure cargo hold. In order to take into account the greater weight, each of the two main landing gears would have been provided with a further, third axle. The HP.111V would have had 12 wheels per main landing gear.
The Handley Page HP.111 would have been powered by either Bristol Olympus or Rolls-Royce Conway engines. However, pre-orders for the Handley Page HP.111 were never received. The competing model Vickers V-1000, which was chosen for production, was never completed and its civilian version Vickers VC7 was never realized. BOAC itself was more interested in the Boeing 707 than in the civil aircraft projects of British industry.
