The MQM-61A was a simple monoplane with a vee tail. It was substantially larger than the MQM-36 Shelduck, and powered by a 94 kW (125 hp) McCulloch TC6150-J-2 flat-six, air-cooled, two-stroke piston engine driving a two-blade propeller. It could tow banners or targets of its own, with two targets under each wing, and also carried scoring devices.
The propellers of a C-130J Super Hercules military transport aircraft. In aeronautics, an aircraft propeller, also called an airscrew, [1] [2] converts rotary motion from an engine or other power source into a swirling slipstream which pushes the propeller forwards or backwards.

Toroidal propellers are most commonly used by the aviation and maritime industries. On drones it is used with thrusts comparable to multirotor drone propellers, and on boats with a notable increase in efficiency. Due to its inaudible frequency, the propellers have also been associated with quiet take off and landing protocols and stealth aircraft.
The drone also features a Wi-Fi module, a GPS-enabled position holding, return-to-home capability, a Naza-M flight control system, and self-tightening propellers. [11] [12] The drone connects to iOS or Android devices via an app, allowing the operator to control the camera and view flight data. Battery capacity was increased to 5200mAh, giving ...
A more serious problem with this type of propeller is a "frozen-on" spline bushing, which makes propeller removal impossible. In such cases the propeller must be heated in order to deliberately destroy the rubber insert. Once the propeller is removed, the splined tube can be cut away with a grinder and a new spline bushing is then required.
Among the designs he tried was the Oehmichen No. 2, which employed four two-blade rotors and eight propellers, all driven by a single engine. The angle of the rotor blades could be varied by warping. Five of the propellers, spinning in the horizontal plane, stabilized the machine laterally. Another propeller was mounted at the nose for steering.
The Mastiff was powered by a German-made "Limbach" two-cylinder, two-stroke motor with thrust generated by a two blade pusher propeller manufactured by "Propeller Engineering & Duplicating, Inc." of San Clemente, California, USA.
