The HP115 is a very low aspect-ratio delta wing research aeroplane built to investigate the slow speed characteristics of the slender delta wing form. This single-seat machine is of all-metal construction with a single swept fin and a fixed, stalky undercarriage. The cockpit is low slung to ensure a clean flow of air into the intake of the single Bristol Siddeley Viper ASV9 of 1, 900 lb static thrust mounted in a dorsal fairing at the rear of the fuselage. The sharp leading edge of the 74º angle swept wing is detachable to allow installation of other shapes than the straight edge fitted in early trials. The HP115, XP841, was flown for the first time on 17th August 1961, at the Royal Aircraft Establishment airfield at Thurleigh, near Bedford. The aircraft was then used for slow speed research related to the BAC-Sud Concorde supersonic airliner, the high speed research being carried out by the BAC Type 221, WG774, the ex-World Speed record holder modified by the fitting of a delta wing of ogival form.
