What force acts on gliders in the air?
Gravity, from the Earth, pulling it towards the ground, and Lift, applied by the air due to pressure difference on the wings (high pressure below the wing, low pressure above the wing). The faster the glider goes, the greater the Lift. Gravity does not change however.
How does convection work on a glider?
If the glider has a roasing chicken inside, it will cause some convection waves, this will lift the Glider up.
How do glider wings work?
The shape of the chord produces lift when moving forward, this lifts the glider.
What is the independent variable of a glider?
The independent variable of a glider, if it is an air glider, would be the thermal updrafts available at any flight. Without effective thermals, it makes it difficult for a glider to maintain lift and develop elevation for sustained glides.
Do different paper airplane designs create more lift than others?
Yes. Some create more lift than the others. Glider paper planes have more lift due to big wings. Paper planes like Classic dart fly faster but for less amount of time.
What are the three forces acting on a glider in flight?
thrust, Lift, weight, and drag.
Do gliders have engines?
Yes and no... Pretty much every glider does not have an engine. A tow plane is used to take the glider up, then it detaches and uses thermals which come from the ground to lift its self up. Just like what a bird does. When a bird flies in circles, it has found a thermal and you will notice it is rising up... On the other hand, Germany has invented a glider with an engine that comes out for take off, and as soon as the glider is in the air, the engine goes back in.
How does a airplane work?
An airplane is a machine used to fly. An airplane uses it's engine to produce thrust to move the aircraft. When an airplane takes off the engine(s) push the aircraft faster and faster. At a certain speed there is enough air flowing over the wings at a high enough speed for the wings to produce lift. Lift pushes the aircraft into the air and keeps it there. When an airplane goes to slow or is pointed at too great and angle, it's stalls, and falls out of the sky. Airplanes are used to carry people and goods over great distances faster and cheaper than many other forms of transport.
What technology was necessary in order for the glider to be functional?
It had to be recognised how airflow helped a wing gain lift
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.
How can a 500Kg glider stay in the air?
For flight to be achieved then you must create a force of lift greater than the weight of the glider. this is achieved by the use of an airofoil. ie the wings of the plane. as an airofoil travels through the air the leading edge cuts the airflow. air flowing over the top of the wings travels faster than the air under the wing Faster air = Lower pressure. As there is lower pressure above the wing the force of lift is created. However to create this airflow the glider must be traveling forward at a sufficient speed to create sufficient lift. Being a form of non powered flight it cannot do this alone. that is why it is towed to to the required altitude. Unhitched, And allowed to fall at a controlled speed (glide) downward . to control the speed at which the glider falls, the pilot uses the pitch of the plane. nose up slows descent, nose down increases rate of descent, but also allows you to pick up forward velocity which can be used to re ascend.
