Abstract: A motor assembly that includes a motor (102) having a rotatable shaft (100), a hub (106) coupled to the rotatable shaft (100), the hub (106) having a propeller indexer (118) to receive a propeller (104), when the propeller (104) is present, a sensor trigger (108) rotatable with the shaft (100) and positioned at a propeller offset angle thetaPROP from the propeller indexer (118), and a sensor (110) coupled to the motor and positioned to detect the sensor trigger (108) so that the propeller indexer (118) may be positioned at the propeller offset angle thetaPROP from the sensor (110) through rotation of the shaft (100) so that said sensor (110) is proximate to the sensor trigger (108).

Abstract: A propeller (70) for an aircraft (20) having a fuselage (22) and a pair of fixed wings (50a, 50b) includes a mounting member (76) secured to at least one wing. At least one blade (72) is rotatably connected to each mounting member (76) and has an airfoil shape. The at least one blade (72) is in a locked condition during take-off and landing of the aircraft (20) extending parallel to a leading edge of the wing and in an unlocked, rotating condition during flight for propelling the aircraft (20).
Abstract translation: 用于具有机身(22)和一对固定翼(50a,50b)的飞行器(20)的螺旋桨(70)包括固定到至少一个翼的安装构件(76)。 至少一个叶片(72)可旋转地连接到每个安装构件(76)并且具有翼型形状。 所述至少一个叶片(72)在飞行器(20)的起飞和着陆期间处于锁定状态,平行于机翼的前缘延伸并且在飞行期间处于解锁的旋转状态以推进飞行器(20) 。
