How is a Helicopter different from aircrafts?
A helicopter is an aircraft that is capable of Vertical Take-Off and Landing (VTOL), as well as hovering in one place and flying in any direction. Unlike fixed-wing airplanes which rely on propellers for propulsion, helicopters have rotating wings, or rotor blades, that provide lift and propulsion. They are commonly used in various applications such as transportation, search and rescue, military operations, aerial photography, and recreational purposes.

Parts of a helicopter
The main components of a helicopter includes the main rotor, tail rotor, fuselage, landing gear, and engine. The main rotor consists of several blades connected to a central hub and is responsible for generating lift by spinning rapidly. The tail rotor, mounted on the tail boom, counteracts the torque produced by the main rotor, allowing the helicopter to maintain its heading. The fuselage is the main body of the helicopter, housing the cockpit, passenger or cargo compartments, and other necessary equipment. The landing gear provides support during takeoff, landing, and ground operations.

Helicopter engine
Helicopters are powered by one or more engines, which can be either piston engines or gas turbine engines. Gas turbine engines are more common in modern helicopters due to their higher power output and better performance. The engines drive the main rotor and other systems, such as the hydraulic system for controlling the rotor blades and other flight controls.

Advantage over aircrafts
One of the key advantages of helicopters is their ability to take off and land vertically, which allows them to operate in confined spaces and access areas that are not easily reachable by other aircraft. They can hover in mid-air, providing a stable platform for tasks such as aerial photography, surveying, or rescue operations. Helicopters can fly at lower speeds and in any direction, enabling them to maneuver more effectively than fixed-wing aircraft in certain scenarios.

Helicopter flight controls
Helicopter pilots require specialized training due to the complex nature of helicopter flight. They must learn to control various flight controls, manage the engine power, and maintain stability during different flight maneuvers. Additionally, they need to be skilled in managing emergencies and adverse weather conditions.
Helicopter control systems
In summary, helicopters are versatile aircraft that offer unique capabilities for a wide range of applications. Their vertical takeoff and landing capabilities, maneuverability, and hovering capabilities make them invaluable in industries such as transportation, emergency services, and aerial work.
