Heya all
im deciding whether to go inot aeronautical engineering and I've been told that i need to kow the basics on how helicopters n etc work? can anyone give me a rough description or a site that says? wat else do u think ill need to know?

Well, you've asked a pretty broad question. In the broadest sense the two things that are most basic are that helicopters turn the "wings" to create a relative wind and thus produce lift where as an airplane moves the entire aircraft to create lift. The tailrotor or tandem rotor (or even the second rotor on the same shaft) counteract the torque produced to turn the main shaft.

You need some basics, so start here:
http://www.helicopterpage.com/
http://www.verticalreference.com/vertical_reference_helo_aero_by_Rey.htm
http://www.copters.com/helo_aero.html (maybe a bit more than basics here)

There are tons of sites out there. Just go to any search engine and look up helicopter aerodynamics or helicopters and you will find a wealth of information.

If you have specific questions, feel free to ask them.

1. What is aeronautical engineering and how does it relate to helicopters?

Aeronautical engineering is a branch of engineering that deals with the design, development, and construction of aircraft and spacecraft. It includes the study of aerodynamics, propulsion systems, and materials used in the construction of aircraft. Aeronautical engineering is crucial in the design and development of helicopters as it ensures that the aircraft is safe, efficient, and can perform its intended functions.

2. What are the main components of a helicopter?

A helicopter has four main components: the fuselage, main rotor, tail rotor, and landing gear. The fuselage is the main body of the aircraft and contains the cockpit, passenger and cargo compartments, and the engine. The main rotor is responsible for lifting the helicopter off the ground and providing lift during flight. The tail rotor is used to counteract the torque produced by the main rotor and allows for the helicopter to change direction. The landing gear consists of wheels or skids that support the helicopter during takeoff and landing.

3. How does a helicopter fly?

A helicopter flies by using its main rotor to generate lift. The rotor blades are shaped like airfoils and, as they rotate, they create lift by pushing air downwards. The angle of the rotor blades can be adjusted by the pilot to control the direction and speed of the helicopter. The tail rotor counteracts the torque produced by the main rotor, allowing the helicopter to change direction. The pilot also uses the cyclic and collective controls to adjust the pitch and lift of the rotor blades, enabling the helicopter to move in any direction.

4. What are some of the challenges in designing a helicopter?

Designing a helicopter presents several challenges, including weight, stability, and control. Helicopters need to be lightweight to achieve lift and maneuverability, but this can be difficult to achieve while still ensuring durability and safety. Maintaining stability is also crucial as any imbalance can cause the helicopter to become unstable and potentially crash. Additionally, controlling a helicopter requires precise movements and coordination, making it a challenging task for pilots.

5. What advancements have been made in aeronautical engineering for helicopters?

There have been numerous advancements in aeronautical engineering for helicopters, including improvements in materials, aerodynamics, and propulsion systems. The use of advanced composite materials has made helicopters lighter, stronger, and more fuel-efficient. Aerodynamic advancements, such as the addition of winglets, have also improved the performance of helicopters. In terms of propulsion, advancements in engine technology have resulted in more powerful and efficient engines, allowing for faster and longer flights.
