What is S in aerodynamics?
The ends of the wing are called the wing tips, and the distance from one wing tip to the other is called the span, given the symbol s. The shape of the wing, when viewed from above looking down onto the wing, is called a planform.
What are the fundamental aerodynamic variables?
In many aerodynamics problems, the forces of interest are the fundamental forces of flight: lift, drag, thrust, and weight. Of these, lift and drag are aerodynamic forces, i.e. forces due to air flow over a solid body.
What are the factors that impact aerodynamics?
The four basic forces [Figure 2-3] acting upon an aircraft in flight are lift, weight, thrust, and drag.
- Lift. Lift is a component of the total aerodynamic force on an airfoil and acts perpendicular to the relative wind.
- Weight.
- Thrust.
- Drag.
- Pressure Altitude.
- Density Altitude.
- Control Characteristics.
- Normal Command.
What are the variables in the drag equation?
The Drag Equation. Drag depends on the density of the air, the square of the velocity, the air’s viscosity and compressibility, the size and shape of the body, and the body’s inclination to the flow. In general, the dependence on body shape, inclination, air viscosity, and compressibility is very complex.
What does gamma mean in aerodynamics?
Appendix D: Aircraft Nomenclature
| ALPHA: | Also α, also angle of attack, the angle between the relative wind and the longitudinal axis of the body, x-z plane, deg. |
|---|---|
| GAMMA: | Also ‘Y, angle between the flight path and the local horizon, deg. |
| L: | Rolling moment, ft – lbf. |
| Local Horizon: | Local “level” reference plane. |
What are the four variables for lift in the lift equation?
The Lift Equation. Lift depends on the density of the air, the square of the velocity, the air’s viscosity and compressibility, the surface area over which the air flows, the shape of the body, and the body’s inclination to the flow.
Does air temperature affect aerodynamics?
Does air temperature affect a car’s aerodynamics? – Quora. Yes, the temperature changes the humidity, and hence changes the density. However, since the change in temperature doesn’t change that much of the density of air, its affect to the aerodynamic performance of the car is usually negligible.
How do you increase aerodynamics?
You’ll also improve aerodynamics by:
- Reducing the use of roof racks.
- Rolling up your windows and turning on the air conditioner at higher speeds, typically above 35 mph.
- Replacing a broken or missing front air dam.
- Lowering your vehicle.
- Running narrower tires.
What is Rho in aerodynamics?
In many textbooks on aerodynamics, the density is given by the Greek symbol “rho” (Greek for “r”). The combination of terms “density times the square of the velocity divided by two” is called the dynamic pressure and appears in Bernoulli’s pressure equation.
