Problems solved by technology

[0003] One problem associated with use or propellers in flying cars is that the propeller blades are relatively sharp, and many road vehicle regulations specifically prohibit the presence of such sharp structures on vehicles used on public roads

Embodiment Construction

[0018] refer to figure 1 and 2 , showing the inclusion of the in-flight configuration ( figure 1 ) and road use configuration ( figure 2 ) dual-purpose vehicle (flying car) aircraft. The flying car includes a body structure 10 that provides a passenger compartment 12 and houses an electric motor (not shown) and a propeller shaft (not shown) that extends from the motor to the rear 14 of the body structure 10, the propeller being mounted on the the rear, as described below. Wings 16 for providing lift and control (via ailerons, not shown) are mounted on top of the body 10 immediately behind the passenger compartment 12 . The wings 16 may be in an extended position for flight use ( figure 1 ) with the folded position for road use ( figure 2 ) to move between. In the folded position, the wing lies along the top of the body 10 with the long axis of the wing lying substantially parallel to the long axis of the body 10 . The folding mechanism is essentially as described ...

Abstract

An aircraft, such as a flying car, comprising a body structure, lift structures (such as wings), control structures (such as fins, elevators, and ailerons), and a motor; a propeller connected to the motor and mounted for rotation about a drive axis to provide thrust; the propeller comprising a hub having a plurality of blades connected thereto; and a plurality of blade housings adjacent the propeller and extending substantially parallel to the drive axis; wherein the blades are mounted on the hub so as to be moveable between an expanded position in which the blades project radially from the hub, and a folded position in which each blade extends axially from the hub so as to lie in a respective blade housing.

Description

technical field [0001] The invention relates to a folding propeller suitable for aircraft. In a particular embodiment, the aircraft is a dual purpose vehicle having a flight configuration and a road use configuration. Such vehicles are generally referred to as flying cars or amphibious aircraft (hereinafter referred to as "flying cars"). Background technique [0002] There have been many previous proposals for the design of flying cars, that is, vehicles that can fully meet the legal and practical requirements for road and flight use. Examples include Terrafugia Transition (WO2007 / 114877), Carplane ( http: / / carplane.de / ), AeroMobil (WO 2013 / 032409) and Moller Skycar ( http: / / moller.com / ). The first three of these examples all incorporate propellers as a means of providing thrust in a flight configuration, specifically a propeller arrangement. [0003] One problem associated with use or propellers in flying cars is that the propeller blades are relatively sharp, and m...
