To lift a 180 lb person 30 ft consistently, a two-bladed propeller is being considered, with calculations suggesting the need for a specific size and power output. The discussion references using a static thrust calculator to determine appropriate propeller and motor specifications. Theoretical mechanics indicate that the induced velocity and power required for lift depend on air density and the weight being lifted. For instance, a small helicopter weighing 700 kg requires approximately 60 kW (80 hp) to achieve lift. Understanding these dynamics is crucial for anyone exploring personal lift systems.
