probably a stall, but they are not that dangerous, if you are trained to get out of them

How does the speed of the rotor affect the amount of lift?

The speed of the rotor directly affects the amount of lift generated by a rotorcraft. As the rotor spins faster, it creates more lift by generating greater airflow over the rotor blades, allowing the aircraft to climb or maintain altitude. Conversely, decreasing the rotor speed reduces lift, potentially causing the aircraft to descend.


What is the lift force in an aircraft?

The lift force is the force acting against the aircraft's weight. For straight and level flight, lift acts in the upward vertical direction and the weight of the aircraft acts in the downward vertical direction. For level flight, lift = weight.


Is lift an unbalanced force?

Yes, lift is an unbalanced force. It acts in opposition to the weight of an aircraft, allowing it to rise or remain in the air. When the lift generated by the wings exceeds the gravitational force acting on the aircraft, the result is an upward acceleration. Conversely, if lift is less than weight, the aircraft will descend.


If an aircraft is flying horizontally then its weight must be balanced by what force?

Lift balances weight. Thrust balances drag.


Why is maximizing the ratio of lift to drag forces desirable?

Maximizing the lift-to-drag ratio is desirable because it allows an aircraft to generate more lift for a given amount of drag, resulting in improved fuel efficiency and range. A higher lift-to-drag ratio also means the aircraft can fly at higher altitudes and speeds, which can be beneficial for performance and overall aircraft capabilities.

What is the difference between angle of attack and positive angle of attack?

Angle of attack may be negative or positive - it's simply the angle between the wing chord line and the oncoming airflow. If it's positive then the aircraft will benefit from the lift that is provided, if it's negative then there is no lift (but there's still drag). This is a potentially dangerous situation, unless you wish your aircraft to descend.


What does the weight of the airplane have to do with the lift of it?

The weight of an aircraft counteracts the lift produced by an aircraft. The heavier an aircraft weighs the greater the lift needed to get off the ground.

How do wingless aircraft produce lift?

The only 'wingless aircraft' are helicopters. These produce lift lift from the rotor blades, which are in fact, long narrow wings.

What is a rotary aircraft?

A rotory aircraft is essentially a helicopter or a type of aircraft that relies on the movement of its wing to produce lift.

What is a loss of lift that can cause an arcraft to crash?

If an airplane exceeds it's maximum angle of attack, or drops below a certain velocity aerodynamic STALL is what occurs. It is characterized by separation of the flow over the top surface of the wing. This phenomenon reduces lift which, if designed right, will cause the aircraft to nose dive. That being said, stall for most airplanes is really only dangerous during take off and landing since there's not much vertical space to recover from the sudden loss of lift.


What is aircraft propeller and what function does it do to the aircraft?

An aircraft propeller is what gives the aircraft power to move it forward (or backward, depending on it's pitch). This enables the aircraft to acquire lift and gain altitude. Propellers are found on some fixed-wing aircraft and autogyros. On helicopters, the blades that lift it and stabilize it are called rotors.


What is the term for the upward force on the wings of an aircraft?

Lift.

What part of aircraft makes flight to take off?

The engines provide forward thrust, allowing the wings to generate lift. It is the lift that allows the aircraft to take off.
