摘要:
A kit for conversion of a snowmobile for use as a personal watercraft by replacement of the skis (10) with steerable flotation 'device' (100) and addition of outrigger flotation 'device' (130) to suspend the track (90) in the water while providing flotation to the chassis (40), along with the flotation provided by the steerable flotation 'device' (100). The kit installs to the snowmobile without removing the track (90) or engine drive, and without interference with operator control systems. Wheels (200) may be included in keels of some hulls (100) to allow for ease of access and egress from water to land.
摘要:
A vertical takeoff and landing craft that utilizes lifting, propulsion and maneuvering (LPM) assemblies comprising a series of blade foils arranged along track elongated loop paths disposed at the sides of a fuselage. These LPM assemblies are provided with control mechanisms enabling lift, attitude changes, altitude changes and directional flight propulsion and control including those needed for hovering as well as vertical takeoff and landing. The LPM assemblies are configured to drive large volumes of air in a manner and scale favorably similar to conventional rotorcraft while in contrast, providing capability for faster flights by eliminating or minimizing speed limiting factors commonly associated with rotorcraft.
摘要:
Disclosed herein is an acceleration system for a link belt-mounted ship. The acceleration system comprises water wheels(10), rotating shafts(20) mounted through the water wheels, link belts(30) surrounding the water wheels and formed an outer peripheral surface thereof at with hook-shaped blades(31), ball bearing units(11) mounted external to the water wheels so that the rotating shafts are inserted therethrough, square pipes(12) onto which the ball bearing units are bolted, hinges(13) bolted onto the square pipes and each hinge having a hinge rod(131) bolted to the hull, and hydraulic cylinders(14) fastened on the square pipes so that they are fixed to the bottom surface of the hull by way of upper brackets(141) and associated pins(143), and fixed to the square pipes by way of lower brackets(141) and associated pins(143). The system can simplify repair works thereof and enables required defective components to be individually exchanged thus facilitating its manufacture.
