The Trident TR-1 Trigull is an amphibious aircraft that was developed by the Canadian manufacturer Trident Aircraft in Burnaby , British Columbia and later in Sydney , British Columbia. The machine was to be offered as a type-approved aircraft. However, as the company ran into financial difficulties, only three prototypes were built.
development and construction
The Trigull was designed based on the Republic Seabee . It is a single-engine, cantilever high-decker with four to six seats and retractable nose wheel landing gear in pusher configuration .
The aircraft is made of aluminum and fiberglass-reinforced plastic . The wings have a wingspan of 41.8 ft (12.7 m ) and an area of 245.2 ft² (22.8 m² ) and have a NACA -23015-R-4 profile . The Continental Tiara 6-285 with 285 PS (210 kW ) or the Tiara 6-320 with 320 PS (235 kW) were originally planned as engines . Later, however, the Lycoming IO-540-M1A5D with 300 PS (221 kW) and the turbo-charged Lycoming TIO-540-J2BD with 340 PS (250 kW) were used. The engineering design includes some innovative features such as support float at the wing tips, which can be retracted and as an extension of the wing surface additional buoyancy produce, into the nasal retractable nose wheel , which during mooring on the water as Fender serves as well as hanging aileron . The Trigull was developed to compete with the Republic Seabee , Lake Buccaneer and the SIAI-Marchetti FN.333 Riviera .
Trident Aircraft was founded in February 1970 to develop the TR-1. The maiden flight of the machine took place on August 5, 1973. The first flight of the second prototype followed on July 2, 1976. On October 28, 1976, the TR-1 Trigull 285 received type certification by the Canadian transport authority Transport Canada . The type certification by the US Federal Aviation Administration followed on December 16, 1976.
The mass production should start early 1980; 43 orders and a further 23 options have already been received. The project received technical support from both Canadair and Grumman Aerospace Corporation . Despite financial support from the Canadian Department of Commerce Innovation, Science and Economic Development Canada and the British Columbia Development Corporation , the company ran out of money and ceased operations in 1980. Although the TR-1 was developed for series production, only three prototypes were built by Trident, two of which were registered ( license plate C-GATE and CF-TRI, later C-FTRI) and flown. The third was used for technical experiments.
The type certificate has been held by Viking Air in Sydney , British Columbia , since 2006 . Viking Air also owns the two prototypes received. In 2003 Viking Air showed interest in manufacturing the Trigull with a turboprop engine . The selling price should be around 400,000 US dollars lie.
