1, Airfoil:

Shape: The airfoil is the shape of the cross-section of the wing, which determines the lift and drag characteristics of the air flowing over the wing.

Key parameters: including camber, thickness, leading edge radius, etc.

Function: Generating lift is the basic condition for an aircraft to fly.

2. Lift:

Cause: the upper and lower surfaces of the wing have different airflow speeds, and according to Bernoulli's principle, the upper surface has fast airflow speed and low pressure. The lower surface air flow is slow and the pressure is high, which creates an upward force.

Influencing factors: airfoil profile, Angle of Attack (that is, the Angle between the wing and the relative airflow), airflow speed, etc.

3. Drag:

Types: including friction resistance, pressure differential resistance, induced resistance and interference resistance.

Action: In the opposite direction of flight, slow down the forward speed of the aircraft.

4. Angle of attack:

Definition: The Angle between the wing string of an aircraft and the relative air flow.

Importance: Changes in the Angle of attack can significantly affect lift and drag.

5. Stall:

Definition: When the Angle of attack increases to a certain extent, the lift generated by the wing no longer increases but decreases.

Consequences: Possible loss of control of the aircraft.

6, Control:

Main control surfaces: aileron (control roll), elevator (control pitch), rudder (control yaw).

Function: The attitude of the aircraft is controlled by changing the position of these control surfaces.

7. Weight and balance:

Importance: The center of gravity and weight distribution of an aircraft have an important impact on flight performance and stability.

Adjustment: The desired center of gravity position is achieved by adjusting the counterweight.

8, pneumatic layout:

Conventional layout: such as normal layout, duck layout, tailless layout, etc.

Impact: Different aerodynamic layouts will have different effects on the aerodynamic performance, stability and maneuverability of the aircraft.

With these basics in mind, model aircraft enthusiasts can improve their skills in the following ways:

Theoretical study: Read relevant books and materials to deepen the understanding of aerodynamic principles of aircraft.

Hands-on operation: Hands-on making and flying models, hands-on learning to adjust and optimize.

Simulated flight: Practice with a flight simulator to understand how the model reacts under different flight conditions.

Exchange learning: Join the model airplane community and exchange ideas with other enthusiasts.

With continuous study and practice, you will be able to better master the flying skills of fixed-wing model aircraft.
