L’ Euro 730 It was the prototype of a British plane from Mach 3, reconnaissance and bomber for the Royal Air Force. It was deleted in 1957 together with other developments of piloted planes as part of 1957 Defense White Paper. During the early days of the Cold War, the Raf V-Bomber Fleet had been entrusted with the role of nuclear deterrent. For the strategic reconnaissance both pre-bombing and post-bombing, an operational requirement was identified in 1954, or. 330, for a plane that could enter the Soviet Union avoiding the enemy defenses. The plane was supposed to have the supercrociera capacity, that is, to maintain Mach speed 2.5 to 60,000 feet (18,300 m), be able to reach Mach 3, and operate at a maximum radius of 5,754 MI (9,260 km). Proposals were presented by the most important British planes manufacturers: the Handley Page HP.100, the Vickers SP4, the English Electric P.10, the Type 730 of the Avro and an unspecified Short Brothers project. Everyone had a futuristic design with delta wing or an extremely tapered form, they were driven by a remarkable number of engines, from 12 of the HP.100, to the 16 mounted horizontally in the back of the Vickers. The English Electric project included ramjets. In 1955 he was assigned to Avro a contract to develop his plane known as Type 730. As a development help, the Bristol Type 188 research plane was built to test the shape of the wings and the effects on the metal of prolonged supersonic flight. The first prototype, planned to fly in 1959, was under construction when the minister, Duncan Sandys, announced the decision to erase his development. The Bristol 188 project however continued. The initial avro 730 was based around a long and thin fuselage with a high ratio between the length of the fuselage and its diameter, a requirement to support high -speed flight. Small quasi-rectangular and raked wings were mounted just behind the exact half of the fuselage. Four Armstrong-Siddeley P.156 engines were mounted, mounted in pairs one above the other on pylons located at the ends of the wings. A conventional roof was not adopted in order not to alter the tapered shape; The cabin included only two small windows they gave on the sides, and only a retractable periscope would be used for vision forward during take -off and landing. The crew would have been made up of three men: the pilot, the navigator and the radar employee. This initial version was expressly understood for the reconnaissance flight, using its “Red Drover” radar to look for objectives to be attacked by the strength of Bombardieri-V that would follow it. With the progress of development, we realized that there was no need for an antenna as large as initially thought, thus freeing about the internal space. The Raf then oriented towards the role of support bomber, which included the radar but also a long bomb compartment that could host both ammunition and additional fuel. Since at that time a high -speed bomber, OR.336, was also studying, the two projects were merged into the new RB.156 specification. This led to a substantial revision of the project. Although the new version resembled a lot to the original, it was overall larger and characterized by a different form of the wings. To increase the wing surface, external flaps were added to the motor supports and the entire wing shape was redesigned to be more similar to a classic delta. The part of the wings internal compared to the engines, which represented about 2\/3 of the total surface, had a 45 \u00b0 arrow, while the smallest external part had a higher arrow, about 60 \u00b0. The engine gondolas had to stay each four Armstrong-Siddeley P.176 engines, for a total of eight. They left with a circular shape on the front and became more square in the back where they ended flush with the wings. The rest of the drawing maintained the characteristics of the previous version, with rectangular canard flaps, the hidden passenger compartment and a large vertical tail fin with a cut delta. For the new version, the reduction to only two crew men was also planned, even if the reason for this is not clear considering that the aircraft could still bring the same equipment, and potentially even more. The bomb compartment would have been tight, but very long 50 feet (15 m), and it was expected to contain a nuclear head missile. The project was started for a suitable nuclear head known as Blue Rosette. ^  Lewis 1980, p. 388.  ^  Polmar 2001, p. 10.
