Some do. A few high performance jet aircraft have a movable wing, called a "swing wing" At low speeds the wing is straight out, but at high speeds the wings fold back. A helicopter is an airplane- a "rotary wing" aircraft. The rotor is not a propeller, but wings that are moved through the air. The wings of regular aircraft also move some- they flex up and down as loads change.

What do airplanes and rockets have in common?
Airplanes and rockets are both vehicles designed for travel through the air/space. They both use propulsion systems to generate thrust for movement and wings/fins for stabilization and control. Both airplanes and rockets rely on aerodynamics principles for lift and propulsion.
Why do airplanes have wings?
because airplanes have wings
Do airplanes with bigger wings fly farther than airplanes with smaller wings?
Not necessarily. Wing size is just one factor that affects an airplane's range. Other factors, such as fuel capacity, engine efficiency, and weight, also play a significant role in determining how far an airplane can fly.
Why do paper airplanes fly?
Paper airplanes fly due to the principles of aerodynamics. When a paper airplane is thrown, the shape of its wings and the angle at which it is thrown create lift, which allows the airplane to stay in the air and glide. The force of gravity pulling the airplane down is counteracted by the lift generated by the wings, allowing the airplane to fly.
How does aerodynamics work on airplanes?
Aerodynamics on airplanes involves the study of how air flows around the aircraft's wings, fuselage, and other components. The shape of the wings generates lift, which counteracts gravity and allows the plane to stay in the air. Control surfaces, such as ailerons and rudders, adjust the airflow to control the plane's movement. Streamlined design reduces drag, allowing the plane to move through the air more efficiently.
Do airplanes have two wings?
All airplanes have at least two wings.
What force of airplanes produced by engines causes air to move over and under wings?
Thrust
Why do airplanes need wings?
airplanes need wings so they can glide and land correctly
What forward movement force of airplanes provideed by ingines cuases air to move over and wings?
Thrust
What do birds and airplanes have the same?
Birds and airplanes both have wings.
Do airplanes have wings?
yes.
Do airplanes usually have 2 wings?
Yes, airplanes usually have 2 wings. 1 wing would be unsteady.
How many wings do airplanes have?
2
What do butterflies and airplanes have in common?
Wings.
Why are airplanes streamlined with rounded instead of square wings and bodies?
if they were square it would be like friction and the airplane wouldn't be able to move
Why are airplanes called airplanes?
The wings of an airplane are near-flat surfaces that plane the air.
How airplanes can fly in air in spite of being heavier than air?
Airplanes are designed to generate lift through the shape of their wings and the speed at which they move through the air. This lift force is created by the pressure difference between the upper and lower surfaces of the wings. By generating enough lift, airplanes can overcome gravity and stay airborne even though they are heavier than air.
