aerodynamics question. Power p to fly a plane.
Has p = mass 3/2 do not know if this means square m by 3/2? That is how i take it to be then you divide this by √s which is cross section of wing.
Figures are m = 124.6kg 3/2 divided by s = √ 36m squared
solution comes up with m 1389/s 6m = 231.5kg m to power of -1
i do not know how to get to figure of 1389?
Aerodynamic power is calculated by multiplying the drag force of the plane by its velocity. This can be represented by the equation: P = Fd * V, where P is power, Fd is drag force, and V is velocity.
The aerodynamic power of a plane is affected by its velocity, air density, and the aerodynamic properties of the plane's shape and design. Other factors such as altitude, temperature, and wind conditions may also play a role.
As altitude increases, air density decreases, resulting in less drag force on the plane. This means that the aerodynamic power required to maintain a certain velocity also decreases. However, at higher altitudes, the air may also be thinner and provide less lift, which can also impact aerodynamic power.
Pilot techniques, such as adjusting the angle of attack or using flaps, can affect the aerodynamic power of a plane. These techniques can help to increase or decrease the drag force, thus impacting the overall aerodynamic power needed to fly the plane.
Yes, there are various ways to reduce aerodynamic power and increase efficiency in flying a plane. This can include optimizing the plane's design for reduced drag, using advanced propulsion systems, and utilizing techniques such as gliding and energy management during flight. Additionally, proper maintenance and cleaning of the plane's surfaces can also help reduce drag and improve efficiency.
