READ THIS - GOOD INFORMATION The wings of an airplane and the rotors of a helicopter both help the object fly. Without those the object could not fly because the wings of an airplane have wind going past it which keeps the airplane in the air. The rotors of a helicopter spin in the wind and help the helicopter fly.
What else can I help you with?
How do wings of penguins and puffins demonstrate convergent evolution?
No. Both are birds and their wings are a derived trait common to all birds. The wings of penguins and bats display convergent evolution.
How do you describe a airplane?
See the related link below for a bunch of helicopter pictures. Looks a lot like big grass hopper.
What are five types of homologies that provide evidence of common ancestry?
limbs wings legs arms and flippers
Compare a bird wing to a butterfly wing What kind of structure does this pair represent?
No they are not. Homologus structures are structures that originated from a common ancestor, they show similarity in anatomy and development even tho they may have different functions. For example the human arm and bird wing are homologus (pentadactyl limb).Bird and insect wings are ANALOGUS, which means they show similar function but show no similar structural relationship.

The engine of an airplane does what?
The engine of an aircraft gives the aircraft power to create lift, either using wings (in the case of an airplane) or rotors (in the case of an helicopter) or both (in the case of an autogyro).
How many wings does a helicopter have?
Helicopters do not have any wings. Airplanes have wings Helicopter has rotors. A helicopter has at least two sets of rotors. One rotor creates lift ( Main Rotor on the top ) & the other prevents the helicopter from spinning in circles( Tail Rotor).
Why should airplane always should have wings?
Not strictly speaking true a helicopter has rotors, not wings, but they function as Rotating Wings and that is how the Patent office views them. trouble is they cannot glide if the power is disabled, no dynamic lift like, err. a surfboard.
What is a difference between how an airplane and a helicopter fly?
A conventional airplane has wings that are rigidly attached to the body of the aircraft. The wings along with the body of the airplane move forward thru the air at speed, creating lift, which makes the airplane rise. With helicopters, the wings (rotors) are mounted on a shaft turned by the engine. The rotor turns, moving the rotor through the air, creating lift. The body of the helicopter does not have to move in any one direction. This means that (within the limits of power) a helicopter can fly left/ right, forwards/ backwards, or straight up/ down.
What is the difference between a helicopter and an airplane?
Helicopters are "rotary wing" aircraft- their wings are the rotor blades. Instead of deriving lift from moving air over the fixed wings of an airplane, a helicopter derives lift by moving the wings through the air.
Why does the rotors spin on an helicopter?
The rotor blades on a helicopter work the same way as wings on a fixed wing aircraft. The air passing faster over the top of the airfoil generates lift. Helicopter rotors spin so that the lift is generated without having to have forward airspeed like a fixed wing aircraft.
What is difference between helicopter vs airplane?
A helicopter flies using a rotor and can hover whereas an aeroplane has wings and aeroplanes can generally hold a bigger amount of people.
Is a helicopter kind of the same as a plane?
An airplane has fixed wings to provide lift to keep it in the air and engines (propeller or jet) to provide thrust for forward movement.A helicopter has rotary wings that when turned by the engine provide both lift to keep it in the air and thrust for movement in any horizontal direction.
What is the difference between a helicopter and a gyrocopter?
A helicopter's rotors are all powered, and a helicopter is capable of hovering. A gyrocopter is pushed forward by a powered propeller. However, the main rotor atop isn't powered by the motor - it's the wind which makes it spin, and that acts as the gyrocopter's wings.
What is the difference between the way a helicopter flies and the way an airplane flies?
airplane uses wings to aid in glight helis use just the force of air pushed off the groun d
What is the name of the helicopter with two propellers used to carry supplies?
Undetermined. All helicopters have 2 rotors; usually a Main Rotor and a Tail Rotor. So, I assume you meant 2 Main Rotors of same diameter.Boeing Ch-47 Chinook - One rotor mounted in the front over the cockpit and one rotor in the rear.V-22 Osprey - Both rotors are mounted on engine pods mounted at the tips of the wings. The engines rotate from helicopter mode to airplane mode. This helicopter just went into operational service after years of development.There are helicopters with no tail rotor. It has two rotors on top. One going clockwise the other going counter clockwise. Called Coaxial rotors or co-rotors are a pair of helicopter rotors mounted one above the other on concentric shafts. The military ones look like jets so even with jet engines. Very nasty looking helicopters.They are much faster and can turn and maneuver much faster. You can look it up. Helicopters with Coaxial rotors. I do not mean the ones with the fan in the tail. These just have wings on the tail.The other one is the NOTAR is the name of a helicopter anti-torque system which replaces the use of a tail rotor. Developed by McDonnell Douglas Helicopter Systems (through their acquisition of Hughes Helicopters), the name is an acronym derived from the phrase no tail rotor but uses air to keep the copter from spinning.
What is a helicopter?
A helicopter is an aircraft that uses rotors rather than traditional wings. The rotors act as airfoils and lift the vehicle, allowing it to hover or manueuver in any direction. Some helicopters are powered by gasoline engines and some by jet turbines. They are employed for a variety of operations including transportation, rescue, medical evacuation, and military operations.
