Web14 de mar. de 2024 · Answer: As the propeller blades of a helicopter spins, it creates a downdraft of air. This pushes the helicopter. The air beneath the blades thus, has greater pressure than the air above them. This momentum in the air creates a lift. To hover the momentum created by the flow of air must be balanced by the lift force of the helicopter. layer of frozen water crossword clue
