The main rotor blade passing frequency is: 5.40 Hz x 2 blades = 10.8 Hz The Doppler shift increases the apparent blade passing frequency to 12 Hz. The theoretical speed of the helicopters was 76 mph based on this shift. how to remove salt from a dish

"WebbThe blades on top of a helicopter form the main rotor. The blades are like narrow "wings" and are shaped like airfoils. An airfoil has a specific shape that allows the helicopter to cut through the air in a way that efficiently produces lift. The part of the blade that passes through the air first is called the leading edge. " - Slow motion helicopter blades

Webb12 mars 2024 · Main rotor thrust opposes gravity and keeps the helicopter aloft. A pilot can vary this thrust by feathering the blades with the collective control. When the vertical component of thrust exceeds gravity the helicopter will accelerate up. Likewise, reduction in thrust causes the helicopter to accelerate down.
