__NOTOC__
The Handley Page HP.32 Hamlet was a British six-passenger monoplane transport designed and built by Handley Page.[1] Only one was built to order of the Air Ministry, first flown with three-engines, later changed to two then back to three engines. DevelopmentIn 1924, the British Air Ministry issued Specification 23/24 for a three-engined six/seven-passenger charter airliner.[2] Handley Page's design to meet this requirement, the Hamlet, was a high-wing three-engined monoplane with a conventional landing gear and room for six passengers. The wing was fitted with leading edge slots and flaps to give good landing performance.[3] The only Hamlet was built at Cricklewood in 1926, and registered G-EBNS. It was first flown on 19 October 1926 powered by three 120 hp (90 kW) Bristol Lucifer IV three-cylinder radial engines.[1] The Lucifer gave rise to excessive vibration, particularly in the centre engine, causing the pilot's instruments to be unreadable, and after a final flight with Lucifer engines on 25 October 1926, it was modified with a smaller fin and larger rudder and the engines were changed to two 250 hp (187 kW) Armstrong Siddeley Lynx radial engines, with the nose engine replaced by additional baggage space, first flying in this form on 19 May 1927.[1][4] This modification eliminated the vibration, but the twin-engined variant was underpowered.[5] In March 1928 it was re-engined again with three 150 hp (112 kW) Armstrong Siddeley Mongoose five-cylinder radial engines although it flew only once in that configuration on delivery to the Royal Aircraft Establishment at Farnborough.[1] The aircraft was scrapped in 1929.[1] Specifications (Lynx-powered){{aerospecs|ref=[1] |met or eng?=eng |crew=two |capacity=six passengers |length m=10.62 |length ft=34 |length in=10 |span m=15.85 |span ft=52 |span in=0 |swept m= |swept ft= |swept in= |rot number= |rot dia m= |rot dia ft= |rot dia in= |dia m= |dia ft= |dia in= |width m= |width ft= |width in= |height m= |height ft= |height in= |wing area sqm= |wing area sqft= |swept area sqm= |swept area sqft= |rot area sqm= |rot area sqft= |volume m3= |volume ft3= |aspect ratio= |empty weight kg=1408 |empty weight lb=3105 |gross weight kg=2268 |gross weight lb=5000 |lift kg= |lift lb= |eng1 number=2 |eng1 type=Armstrong Siddeley Lynx radial |eng1 kw=164 |eng1 hp=220 |eng1 kn= |eng1 lbf= |eng1 kn-ab= |eng1 lbf-ab= |eng2 number= |eng2 type= |eng2 kw= |eng2 hp= |eng2 kn= |eng2 lbf= |eng2 kn-ab= |eng2 lbf-ab= |max speed kmh=183 |max speed mph=114 |max speed mach= |cruise speed kmh= |cruise speed mph= |range km= |range miles= |endurance h= |endurance min= |ceiling m= |ceiling ft= |glide ratio= |climb rate ms= |climb rate ftmin= |sink rate ms= |sink rate ftmin= |armament1= |armament2= |armament3= |armament4= |armament5= |armament6= }}{{aircontent |see also= |related= |similar aircraft= |sequence= |lists= }} ReferencesNotes1. ^1 2 3 4 5 Jackson 1973, p320-321 2. ^Barnes 1976, p.252. 3. ^Barnes 1976, p.254. 4. ^Barnes 1976, pp.255-257. 5. ^Barnes 1976, pp.257-258.
