De Hantige pagina HP.115 was een Brits deltavleugelonderzoeksvliegtuig gebouwd door Handley Page om de lage snelheidsafhandelingskenmerken te testen die te verwachten zijn van een supersonisch lijnvliegtuig met slanke deltaconfiguratie. Het maakte deel uit van het Britse supersonische vliegtuigonderzoeksprogramma, uitgevoerd in de jaren 1960 en gesponsord door het ministerie van Bevoorrading, dat uiteindelijk de Concorde produceerde.

General Characteristics and Role

The Handley Page HP.115 was a small, experimental British research aircraft built to investigate the flight characteristics of an extremely slender delta wing at low speeds. It was part of a major research program in the United Kingdom aimed at developing the supersonic transport—the eventual Concorde. The HP.115’s specific purpose was to determine the handling qualities and low-speed stability needed for landing the proposed supersonic airliner. The aircraft had a fixed tricycle undercarriage and a high-mounted engine. Only one prototype was ever built (serial number XP841). Although limited in speed and range, the HP.115 successfully completed its research objectives, logging nearly 400 flights before being retired.

Powerplant and Performance

Engine: 1 x Bristol Siddeley Viper 9 turbojet engine.
Thrust: 8.41 kN (1,890 lbf).
Wing Sweep: Extremely slender delta wing with a 74.7° leading-edge sweep, which was the key experimental feature.
Maximum Speed: Approx. 399 km/h (248 mph; 215 kn).
Service Ceiling: 5,000 m (16,400 ft).
Crucial Contribution: The flight data collected from the HP.115 was vital in confirming the stability and control characteristics that would be incorporated into the Concorde’s design.

Status and Legacy

Testing Period: The HP.115 carried out research flights at the Royal Aircraft Establishment (RAE) Bedford between 1961 and 1974.
Retirement: The sole prototype was retired from flying in 1974.
Preservation: The single Handley Page HP.115 is now preserved and on public display at the Fleet Air Arm Museum at RNAS Yeovilton, Somerset, UK.
