What are the effects of excessive weights on a helicopter?

Operating above a maximum weight could result in structural deformation or failure during flight if encountering excessive load factors, strong wind gusts, or turbulence. Weight and maneuvering limitations also are factors in establishing fatigue life of components.

How far can a helicopter fly without refueling?

Most of the helicopters can fly up to 5000 feet up in the air for about 600 miles when it runs out of fuel reserve. There are different types of helicopters, such as the military, private, and even commercial ones.

How much fuel do helicopters hold?

Generally, small piston-powered helicopters use between 6-16 gallons of fuel per hour. Large, turbine-powered helicopters can use a minimum of 20 gallons of fuel per hour with some going through up to hundreds of gallons an hour.

Why should you not touch a hovering helicopter?

Helicopter rotor blades can generate static electricity. In moist air conditions, electricity can build up. This will be discharged when the helicopter earths or attachments come into contact with the ground. This is not a hazard to those on the helicopter, unless a passenger steps down from a hovering helicopter.

How does center of gravity affect aircraft performance?

The relationship between aircraft performance and CG location is simple: by moving the CG forward and aft, you change the amount of tail down force and lift you need for stable flight. If you need more lift, you create more induced drag, and your performance goes down.

Can helicopters run out of gas?

As you have probably worked out, a helicopter can only fly as far and as long as it has fuel in its tank. When the fuel runs out, a helicopter will either have to stop and refuel or refuel in-air. Only military helicopters such as the Sikorsky CH-53E Super Stallion and HH-60G Pave Hawk are able to refuel in-air.

What does helicopter use as fuel?

Aviation kerosene, also known as QAV-1, is the fuel used by airplanes and helicopters equipped with turbine engines, such as pure jet, turboprops, or turbofans.

Can a helicopter fly over Mt Everest?

In 2005, Didier Delsalle became the one and only person to ever land a helicopter on the summit of the earth’s highest point, Mount Everest, at an altitude of 8,849 metres. There’s a reason helicopters on the summit of Everest aren’t a common occurrence.

How does center of gravity affect helicopter flight characteristics?

– Helicopter Study Guide How do changes in center of gravity (CG) affect helicopter flight characteristics? The aircraft manufacturer sets the helicopter’s center of gravity limits. If operating outside of these limits, the helicopter may be uncontrollable in certain situations.

What are the effects of CG on a helicopter?

The effects of CG are a reason to perform a weight/balance calculation before each flight. When the CG is forward of limits, there may not be enough aft cyclic travel to stop the helicopter, in particular during the flare at the end of an autorotation.

What is an autorotative descent in a helicopter?

In a helicopter, an autorotative descent is a power-off maneuver in which the engine is disengaged from the main rotor disk and the rotor blades are driven solely by the upward flow of air through the rotor. [Figure 11-1]In other words, the engine is no longer supplying power to the main rotor.

What is gliding in a helicopter?

In effect, the blades are “gliding” in their rotational plane. Autorotation. In a helicopter, an autorotative descent is a power-off maneuver in which the engine is disengaged from the main rotor system and the rotor blades are driven solely by the upward flow of air through the rotor.
