The albatross uses this type of soaring to support its multi-year voyages at sea. Because the air is rising, the bird can maintain its height relative to the ground. Soaring flight is a special kind of glide in which the bird flies in a rising air current (called a thermal). But there is also drag (air resistance) on the bird’s body, so every now and then, the bird has to tilt forward and go into a slight dive so that it can maintain forward speed. As the wings move through the air, they are held at a slight angle, which deflects the air downwards and causes a reaction in the opposite direction, which is lift. The wings are held out to the side of the body and do not flap. When a bird is gliding, it doesn’t have to do any work. Wing loading tells you how fast a bird or plane must fly to be able to maintain lift: wing loading = weight/wing area (kilograms per square metre).Ī smaller wing loading number means the bird/plane can fly more slowly while still maintaining lift and is more manoeuvrable. The tail rotor is boxed in allowing for safe cargo loading and unloading capability. So smaller-winged birds (and planes) need to fly faster to maintain the same lift as those with larger wings. The UH-72A Lakota, manufactured by Eurocopter, is a twin-engine, single four-bladed main rotor, single two-bladed tail rotor, light-duty helicopter utilized by the U.S. ![]() Larger wings produce greater lift than smaller wings. Also, the angle of the wing (tilted) deflects air downwards, causing a reaction force in the opposite direction and creating lift. This means the air is moving more quickly over the top surface of the wing, reducing air pressure on the top of the wing and creating lift. The increased speed over a curved, larger wing area creates a longer path of air. The shape of a bird’s wing is important for producing lift. ![]() With life-like features, your child can turn the steering wheel left and right to get it moving, to slow.
