I have a doubt that instead of the rotor blades in the helicopter why can't we use a propeller for thrust producing
This is how autogyro or gyrocopters work, the propeller provides thrust to drive the gyrocopter forwards, and the air flowing through the main rotor causes it to spin and produce lift, so the main rotor is not powered.majid hussain said:I have a doubt that instead of the rotor blades in the helicopter why can't we use a propeller for thrust producing
A propeller on a helicopter works by creating lift and thrust through rotating blades. As the blades spin, air is forced downwards, creating an upward force that lifts the helicopter off the ground. The angle of the blades can be adjusted to control the direction and speed of the helicopter's flight.
The most common materials used to make helicopter propellers are aluminum, titanium, and composite materials such as carbon fiber. These materials are chosen for their strength, durability, and light weight to help improve the performance and efficiency of the helicopter.
Helicopter propellers are carefully designed using computational fluid dynamics (CFD) software, wind tunnel testing, and real-world flight testing. The shape, size, and angle of the blades are all taken into consideration to optimize performance and reduce noise and vibration.
A fixed-pitch propeller has blades that are fixed at a specific angle and cannot be adjusted during flight. A variable-pitch propeller, on the other hand, has blades that can be adjusted to change the angle and optimize performance for different flight conditions.
Helicopter propellers require regular maintenance to ensure they are in good working condition. This typically includes cleaning, inspection for damage or wear, and balancing the blades to prevent vibration. Any necessary repairs or replacements should be done by a qualified technician to ensure safe and efficient operation of the helicopter.
