How can a 500 kg glider stay up in the air?

Question

Please reply a.s.a.p

Answer 1

This is an Engineering question.

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.

Answer 2

The glider moves forwards and the airflow over the wings lifts the glider. However it would go back towards the earth without extra power. This power comes from the skill of the pilot in finding regions of rising air. A day with sun and fluffy clouds is ideal because under each cloud is a "thermal" where the air is rising. Pilots just circle in these to get height then move on to the next thermal.

Obviously at night there are no more thermals and its time to go home.

Answer 3

Its descending in the air around it, say at 1.2m/s, but its wings are basically converting some of its downwards force into forward momentum

If it enters a rising column of air, moving upwards faster than it descends, this will mean the glider travels upwards, like someone walking down an upwards escalator, even though they are moving down the stairs they still end up moving upwards

Its weight is insignifigant, as the moving air can weigh many millions of tonnes itself

Answer 4

Well If the glider has long wing span, and a good weight distribution, then of course it will stay up in the air for a long time. Most planes weigh more than that, and they stay up, same concept.

Answer 5

It will stay up in air,if it has been designed to do so. Especially for a glider light weight, long wing span, high lift coefficient are important,since it has no power of its own and lift has to come from the camber and wing span and area.

The heavier the plane, the larger the wings.
