Avro 739

History of the Avro 739

The British electric "Canberra" was a product of the British aviation industry during the Cold War (1946-1991) and appeared immediately after World War II. This type is a light/medium jet bomber that has also served much longer than expected in reconnaissance missions. According to some in RAF circles, the type became obsolete when it entered service in May 1951, but its career continued until June 2006. 900 were built for the UK, while the Australians bought 49.

Even the Americans adopted the model of the Martin B-57 "Canberra" (detailed elsewhere on this page).

With this in mind, British war planners were already considering a successor to Canberra, and the only design to emerge in the interim was the technically impressive British Aircraft Corporation (BAC) "TSR.2" (detailed elsewhere) . this page). This tactically focused supersonic strike and reconnaissance platform is the culmination of years of research and development in the UK aviation industry and paved the way for three prototypes before the Labour government ended its future.

The aircraft first flew on September 27, 1964, and was eventually fulfilled by a combined force of Blackburn Corsairs and McDonnell Douglas F-4 Phantom IIs.

However, TSR is exceeded. 2 A plethora of design options emerged that were suggested by ordinary players in the British aviation industry at the time, including Gloster, de Havilland and Hawker. Avro also participated in this high-level initiative and developed its own plan in 1958, interpreting the requirement as "Avro 739" or Type 739. Just like TSR. 2, The Type 739 is a twin-engine swept-wing monoplane with a crew of two.

The company expected their aircraft to make its first flight by the end of 1961.

In the Type 739, the crew sits in tandem behind a sharp, pointed radar housing nose cone assembly. The fuselage ridges blocked rearward visibility but increased the internal volume for equipment and fuel (the latter were also carried on the thin-winged main aircraft).

The twin-engine layout is traditional, with each unit sitting side by side in the center rear of the long fuselage. Air intakes are mounted along the sides of the fuselage with thrust cones to draw the intakes inside, while the engines exhaust through traditional circular ports in the stern.

The main aircraft is the mid-mounted element, located aft amidships, swept back along the leading and trailing edges (less aft). The tail contains a vertical fin along with all moving horizontal surfaces for the required stability and control.

A retractable tricycle landing gear (with wheels) for ground operation, each element (1 x nose bone and 2 x main legs) retracts into the fuselage.

Internal weapons bays are designed to house primary weapons, while external equipment is planned for drop armor and additional ordnance. For reconnaissance missions, the aircraft will carry a camera bag containing four camera units.

The aircraft will be made primarily of aluminum. Like other supersonic feats of the time, titanium formed a key component that required tighter thermal tolerances when increasing speed.

Avro maintains several afterburner turbofans for their Type 739, including entries from Bristol and Rolls-Royce to provide the required thrust. Experimental Rolls-Royce RB.

The 142B Medway was the most likely candidate for this period, described as a large, low-bypass turbofan engine, although only nine were completed between 1959 and 1963.

The aircraft has a barrel length of 80.8 feet, a wingspan of 41.2 feet, and a combined weight of nearly 91,000 pounds under full/extreme load. Top speeds are estimated to be in excess of Mach 2.0, with a full-service ceiling equivalent to 40,000 feet. Given the performance characteristics of TSR. As shown in Figure 2, the Avro 739 may have a climb rate of 15,000 feet per minute and a total range of 2,900 miles. Bomb payloads range from 7,000 pounds to 10,000 pounds and include air-launched rockets, conventionally dropped bombs and even nuclear warhead types, as well as air-to-surface and radar-guided air-to-surface missiles.

For a while, the Avro 739 was thought to be a purpose-built high-speed interceptor - meaning advanced radar and AAM support.

Nonetheless, the Avro 739 project never got past the paper stage.

Monoplane

Designed to use a single main wing main aircraft; this is the most popular arrangement of main aircraft.

Central Install

The main aircraft is mounted below the center on the sides of the fuselage.

swipe back

The floor plan features a wing sweep along the leading edge of the main aircraft, which increases operating speed.
