Development

In the early 1950s, The pioneering Handley Page Limited aircraft company founded by Sir Frederick Handley-Page, designed a fast new short-range passenger aircraft intended to replace the venerable Douglas DC-3. The design, orignally known as the HPR-3 Herald, emanated from the drawing office at Handley Page (Reading) Limited - the former Miles Aircraft factory site, which developed an earlier design; the Miles Marathon. The Herald was an extensive rework, and bore only a superficial resemblance to the original concept of the Marathon. The HP Reading divison produced a modern design which had excellent flight and performance characteristics, but the company made a serious misjudgment. The Douglas DC-3 is a fixed-wing, propeller-driven aircraft, which revolutionized air transport in the 1930s and 1940s and is generally regarded as one of the most significant transport aircraft ever made (also see Boeing 707 and Boeing 747). ... Miles Aircraft was a British manufacturer of light civil and military aircraft. ... The Handley Page (Reading) H.P.R.1 Marathon was a British civil 20-passenger light transport produced by Handley Page (Reading) Limited of Woodley Aerodrome, Reading, England. ...

HP originally configured the Herald with four Alvis Leonides Major piston engines of 870 hp (650 kW) each. The Rolls-Royce Dart turboprops were already showing proven success in the Vickers Viscount. HP failed to take enough account early enough in the Herald design phase, of the market desire for the new turboprops. This delay was to prove a costly mistake for the company. The Alvis Leonides and Leonides Major were British piston aero-engines that found most use in helicopters The Leonides was developed at the start of the Second World War. ... Components of a typical, four stroke cycle, DOHC piston engine. ... The Viscount was a medium-range turboprop airliner introduced in 1953 by Vickers-Armstrongs, making it the first such aircraft to enter service in the world. ...

However, the Herald was advanced in many ways for the time. Its pressurised cabin up to 30,000ft, could seat up to 44 passengers in the series 100 and the aircraft could exceed 300mph in level flight. Initial climb rate was over 1800ft/min. The first "Herald" prototype, G-AODE, first flew on August 25, 1955. Although Queensland Airlines, Australian National Airways, and Lloyd Aereo Colombiano had initially placed 29 orders, these were later cancelled with only the first prototype completed. As a result Handley Page belatedly realised it had to make a major change to the engine configuration, if the Herald was to have any chance in the market. Cabin pressurization is the active pumping of air into the cabin of an aircraft to increase the air pressure within the cabin. ... August 25 is the 237th day of the year in the Gregorian calendar (238th in leap years), with 128 days remaining. ... This is a list of aviation-related events from 1955: Events February February 26 - George F. Smith becomes the first person to survive a supersonic ejection, from a North American F-100 Super Sabre travelling (Mach 1. ... Australian National Airways was the Australias predominant carrier from the mid-1930s to the early 1950s. ...

To recover the project at such a late stage, and in which there had been a very substantial investment already, Handley Page decided to press ahead with the Herald project, with a new uprated version, reworking the wing to use Rolls-Royce Dart turboprops fitted with 12.5ft variable pitch four-bladed Dowty Rotol props. They also lengthened the fuselage by 20 inches (50.8 cm). With the first prototype flying in 1958. Now designated the HPR-7 Dart Herald, the new aircraft entered production in 1959. The first order being placed by BEA. The Rolls Royce Dart was a long-lived turboprop engine. ... A schematic diagram showing the operation of a turboprop engine. ...

The Herald attracted much interest around the world because of its astonishing short field performance and excellent flight characteristics, but Handley Page failed to close many of the deals, as the F-27, and the HS748 had become rival offerings, both of which were significantly cheaper. There has been some speculation about the origin of the F-27 design, which first flew earlier than the Herald in turboprop configuration. A key design feature of the Herald was the high mounted wing but notably with an upswept dihedral. Comparatively, pilots reported that the Herald flew like a dream; very stable in the air, and some credit was due to Handley Page for this useful wing design feature that made the Herald so stable and yet highly manoeuverable. The company's wing design office had garnered a reputation over many years for advanced wing design.

Despite the rework, that transformed the HPR-3 to the HPR-7 Herald, only four of the 47 seat Series 100's were built. HP realised they needed a yet larger version. HP turned to Series 200 production, which featured a further 40 inch (1.07 m) stretch of the fuselage, seating 56 and corresponding increased weights. Production began in 1961. The first production model was delivered to Jersey Airlines in January 1962. However, by this point all sales momentum had been lost, and only 36 examples of this major production model were eventually built.

The Herald 400 was specially developed in 1964 as a "tactical transport" built for the Royal Malaysian Air Force, with side loading doors and a strengthened cabin floor. HP suspected that the Herald was still too small and so a 60-seater series 700, powered by Dart 532's and having increased fuel and weights was designed. The Royal Malaysian Air Force (Malay: Tentera Udara DiRaja Malaysia) was formed in 1958 as the Royal Malayan Air Force (Tentera Udara Diraja Persekutuan). ...

A late attempt was made to revive sales when speculative production commenced on 8 series 700 airframes. The project was cancelled as several of the airframes were approaching completion. The partially completed airframes were said to have been scrapped; although there have been some reports that they remain mothballed, their existence or whereabouts remain unknown. The 50th, and last, Herald (a series 200 for Israel's Arkia) was flown and delivered in August 1968. Arkia Israeli Airlines is an airline based in Israel and uses the IATA designator IZ. On November 28, 2002, at the same time that the Kenyan hotel bombing occurred, an Arkia Boeing 757 was narrowly missed by two anti-aircraft missiles. ... This is a list of aviation-related events from 1968: Events January January 21 - a US Air Force B-52 Stratofortress crashes in the sea near Thule AFB Greenland, carrying four nuclear weapons. ...

It is widely thought that the misjudgments made during the Herald project, necessitating major design changes late in the design cycle, was the company's fatal mistake. Handley Page went into voluntary liquidation on the close of its books on 31 March 1970. The profitable HP137 Jetstream operation and drawing and design staff were the only useful parts of Handley Page left, but it was not enough for the company to survive. HP made a series of catastrophic errors judging the changing needs of the airlines. The Jetstream operation was sold and transferred to Scottish Aviation, later to become a subsidiary called Jetstream Aviation. This company was later acquired by and absorbed into BAe. The Jetstream went on to be a successful commuter offering.

The Herald's last ever passenger flight was operated by Air UK in 1985. A durable aricraft capable of being heavily worked, many continued on as freighters, plying the night sky across Britain and the near continent, for several operators including Royal Mail, Channel Express, DHL & Elan, transporting papers, milk, parcels, post, tomatoes, flowers, and many other goods round the clock, but by 1999 the only one remaining in service, was a series 400 [G-BEYK] with Channel Express; it was retired at the end of March that year. The most similar design in service today is the DeHavilland Canada / Embraer DASH-8; a similarly configured twin turboprop STOL which also employs a high mounted high lift wing.
