摘要： A propulsion system for an aerial vehicle or toy aerial vehicle is disclosed. The system comprises a ducted fan or shrouded propeller drive system for driving the vehicle along ground, the ducted fan or shrouded propeller drive system operating in a plane and having a peripheral ground-engagement part or hubless wheel. The system further comprises a ducted fan or shrouded propeller comprising one or more blades rotatable about a ducted fan or shrouded propeller axis for producing thrust, wherein the ducted fan or shrouded propeller is mounted as such that it may tilt or rotate so that during ground travel it may be in the same plane as the hubless wheel and during operation of the ducted fan or shrouded propeller for flight the blades pass through the plane and inside the hubless wheel. In this way, the ducted fan or shrouded propeller blades of the drive system are protected from blade strikes on obstacles and personnel operating around the ducted fan or shrouded propeller drive system are protected from harm from exposed rotors or blades with no duct or shroud surrounding them.

摘要： A vertical take-off and landing aircraft is shown. The VTOL aircraft has a main wing having a left wing and a right wing configured as folding wings, and one or more of a foreplane, having a left canard and a right canard configured as folding wings, and/or a tailplane, having a left stabiliser and a right stabiliser configured as folding wings. Each one of the folding wings has a fixed inboard section and a folding outboard section. The folding outboard section is downwardly foldable to a landing condition to support the aircraft on a surface.

摘要： An amphibious aircraft has a tricycle landing gear that is fixed. Each member of the landing gear is protected in the forward direction by a hydrodynamic protector, or vane, or shoe, such as may tend to create lift when brought into engagement with water, as during landing. The landing gear protector vanes may be mounted to move with extension and retraction of the landing gear. The landing gear wheels protrude to extend partially downwardly proud of the sole of the shoe. The shoes may include sacrificial wear members for ground engagement.

摘要： Attachment brackets are disclosed which are configured to be removably mounted on aircraft landing gear, e.g., by bolting the bracket to the landing gear. The attachment brackets may be used to secure skis, pontoons, or other landing equipment to the landing gear of the aircraft. In preferred implementations, the brackets are bolted on using existing factory drilled holes in the landing gear.

摘要： An apparatus with wheels which may be removably attached to either of the skid type landing rails of a helicopter. A generally U-shaped attaching member is adapted to be removably attached to either of the rails. A support member has its bottom end pivotally coupled to the top of said attaching member. Structure connected to said support member has an engaging end adapted to engage the top portion of said rail when said attaching member is attached to said rail. The central portion of a generally U-shaped axle member is pivotally coupled to the upper end of the support member. The axle member has two outwardly extending arms with wheels attached thereto such that the wheels will be located on opposite sides of the rail. One end of a cylinder is pivotally coupled to said structure. Said cylinder has a piston which is pivotally coupled to the central portion of said axle member offset from the axis of said central portion. When the piston is retracted, the wheels are at a position such that the rail engages and is supported by the ground. When the piston is extended, the wheels are moved to a position to lift and support the rail above the ground.
