| 释义 |
The Supermarine Sea Urchin was an unbuilt British racing biplane flying boat designed by the Supermarine Aviation Works to compete in the 1924 Schneider Trophy. It was to be a single seat biplane, powered by a Rolls-Royce Condor V-12 water-cooled engine buried in the fuselage, driving a pusher propeller mounted on the upper wing via geared shafts. It was abandoned without being built owing to problems with the engine and the transmission required to drive the propeller.[1] Specifications{{aerospecs|ref= |met or eng?=eng |crew=1 |capacity= |length m= |length ft= |length in= |span m= |span ft= |span in=0 |width m= |width ft= |width in= |height m= |height ft= |height in= |wing area sqm= |wing area sqft= |empty weight kg= |empty weight lb= |gross weight kg= |gross weight lb= |eng1 number=1 |eng1 type=Pusher |eng1 kw= |eng1 hp= |eng2 number= |eng2 type= |eng2 kw= |eng2 hp= |max speed kmh= |max speed mph= |cruise speed kmh= |cruise speed mph= |range km= |range miles= |endurance h= |endurance min= |ceiling m= |ceiling ft= |climb rate ms= |climb rate ftmin= }} See also{{aircontent|see also=
