Handley Page (Reading) HPR-3 Herald
Handley Page (Reading) HPR-7 Herald




A medium‑sized transport designed to take the place of the DC‑3, the Handley Page HPR‑3 Herald design shows an essentially straight forward approach ­with four piston engines, a high‑wing layout and a fuselage designed to carry 44 passengers, freight, or mixed loads. It is to be pressurized to a relatively low differential, and will carry a full payload of 10,705 lb. for a no reserve range of 350 st. miles, or 4,650 lb. for a full‑tank range of 2,050 miles.
Two prototypes were being built in 1954.
The Herald first flew on 25 August 1955 from Radlett, powered by four Alvis Leonides piston engines. Airborne for 30 minutes, the pilot was H.G.Hazelden.
Handley Page HPR.3 Herald
The first Handley Page Herald completed 125 hours flying in a year and received a Special Category of C of A in 1956.
By 1956 the Herald had been ordered by Queensland Airlines, Australian National Airways, Lloyd Aereo Colombiano and Air Kruise.


The prototype Dart-engined Herald made its first flight on 11 March 1958 and the first production Herald Series 100 flew on 30 October 1959. The Series 100 accommodated between 38 and 47 passengers. The Series 200 was the main production version with a forward fuselage 1.07m longer than that of the Series 100. Accommodation was provided for 50-56 passengers. Powered by two Rolls-Royce Dart 527 turboprops of 2,150 shaft hp, its maximum cruise speed is 274 mph.




In 1960 Handley Page were offering both the Leonides Major and Dart powered versions.


The Series 300 (a modified Series 200 developed to meet US airworthiness requirements) was followed by the Series 400 military transport with a side loading door and accommodation for 50 troops, paratroops, 24 stretchers or freight, eight of which went to the Royal Malaysian Air Force. The projected Series 500 was followed by the Dart 532/9 turboprop-engined Series 600.



The final two versions were the Series 700 long-range version of the Series 600, accommodating up to 60 passengers or 52 passengers and baggage over 1,980km stages, and the Series 800 military version of the 700.

By 1958, when they offered an alternative version powered by Rolls-Royce Dart turboprops, the Fokker F 27 had cornered the market. Only 48 aircraft were produced.
