Most people have heard of or seen air shows where various airplanes show off their skills and perform different maneuvers, but is it possible for helicopters to do the same thing? Learning to fly helicopters should be mastered first before trying these tricks, and it also depends on the design of the helicopter you are piloting. For those who have wondered, can helicopters do loops? However, even model helicopters would have to meet certain requirements beforehand.
In other words, a helicopter has to be built to take the kind of abuse often heaped on it when loops are desired. Otherwise, it would likely cause damage to the airframe or other parts of the helicopter. Unfortunately, the much-smaller tail rotor makes a lot of noise and is often easily damaged. What are red helicopters used for? Although at Devon Air Ambulance we use a red helicopter to deliver urgent critical care to patients on scene , red helicopters can be used for all sorts of different services around the world, often to do with lifesaving, such as coast guards or mountain rescue.
In addition to moving up and down, helicopters can fly forward, backward and sideways. This kind of directional flight is achieved by tilting the swash plate assembly with the cyclic , which alters the pitch of each blade as it rotates. As a result, every blade produces maximum lift at a particular point.
Blue Thunder is the helicopter in the s American titular film and television series. After the film and TV series was made, both helicopters were sold to Michael E. Grube , an aviation salvage collector in Clovis, New Mexico. It was the first light twin-engine helicopter in the world, and the first rotorcraft that could perform aerobatic maneuvers such as inverted loops. As a general rule, helicopters usually fly around 2.
This translates to a distance of roughly miles , which means that they can fly a lot farther than many people realize before they have to stop. It also varies depending on the type of flying involved, e.
Each helicopter has a maximum endurance of approx two hours. The average piston-engine helicopters have a flight range of around miles, while the faster gas-turbine powered helicopters can fly to around miles on a single tank.

The pilot needs to carry enough speed to get the helicopter to the top of the climb and pull it over the top, but too much speed would impose very high loads on the rotor system when coming out of the loop leading to severe overspeeding of the main rotor. The first documented helicopter to complete a loop was a Sikorsky S in with Harold E.
You can see an old 8mm recording of the event here:. Helicopters are designed to be flown with the weight of the helicopter suspended below the main rotor blades. Rotor blades are designed in such a way to be able to droop when not rotating and cone upwards slightly when rotating under load.
When high loads are placed on the main rotor blades in the opposite direction to which they are designed this can result in a blade failing. For the main rotor blades to produce lift, the pitch angle is controlled by the pilot to a create positive pitch angle on each main rotor blade. This is like sticking your hand out of a car window when you were a kid. When your hand was flat it stays put, when you begin to turn your thumb to the sky, your hand gets a positive pitch angle and begins to rise.
For a helicopter to fly upside down for a prolonged period of time its main rotor blades would need to be designed to take loads in both the regular way up and then when inverted. The helicopter would also need to be able to give the main rotor blades negative pitch to be able to create lift directed towards the ground when inverted. Only some helicopters can put the rotor system into a degree or two of negative pitch angle, a fairly common feature for helicopters designed for Naval work. The feature of negative pitch is used to help push the helicopter to the deck of a ship until it is secured by crews upon landing, but this also helps in its aerobatic role, but a degree or two of negative pitch is not enough to keep the helicopter in an inverted level flight.
The oil system in the engines and gearbox would have to be pressurised to ensure all the moving surfaces to not become starved of oil when inverted. The fuel sytem would have to be pressurized to ensure the fuel supply remains constant when the helicopter is inverted.
The list goes on and on. There is no helicopter at this time the can fly for prolonged periods inverted because there is no commerical need for one to do that. Without the commericial need, no manufacturer is going to spend billions of dollars developing a helicopter that can do this.
The closet helicopters that would come close to flying inverted for more than a few seconds are the Westland Lynx and the BO
