Why do military helicopters have a pole on the front?

This is a refueling probe, which allows for midair refueling.

What is the pole sticking out of the front of a helicopter?

If the pole pokes out the front, it is a refuelling probe. During long search and rescue missions (CH-47 Chinook, CH-53 Stallion/Jolly Green Giant, H-60 Black Bird), they like to top off fuel tankers from KC-30 Hercules tankers. They prefer prop driven tankers that can fly slow enough for helicopters.

What is the long rod in front of a Chinook helicopter?

The long rod in fromt of the Chinook helicopter is the aerial refueling probe.

Why do helicopters tilt forward?

As a helicopter rotor is rotating about its vertical axis, the blades are constantly changing, not only in location, but also in pitch, and more importantly in angle with respect to the vertical axis. It is this variation in angle that gives the helicopter a forward motion.

Why do helicopters hover in one spot?

As the propeller blades of a helicopter slice through the air, it creates a strong wind. The wind moves downward pushing the helicopter. The air beneath the blades thus, has greater pressure than the air above them. … This is what enables a helicopter to go straight up or down or hover over one spot.

Can helicopters refuel in flight?

Helicopter in-flight refueling (HIFR) is a variation of aerial refueling when a naval helicopter approaches a warship (not necessarily suited for landing operations) and receives fuel through the cabin while hovering.

Where are the Chinooks based?

The UK operates 60 Chinook twin-rotor aircraft, based at RAF Odiham in Hampshire. A heavyweight of the battlefield, Chinook can carry up to 54 troops or 10 tonnes of cargo. It is primarily used for troop and load carrying but performs a crucial secondary casualty evacuation role.

How much can a Chinook lift?

Payload: up to 55 troops or around 22,000lb (10,000kg) of freight. Armament: two 7.62mm M134 Miniguns and one 7.62mm M60D machine gun.

Can a Chinook helicopter carry a tank?

The Chinook is equipped with two T55-GA-714A turboshaft engines, which are pod-mounted on either side of the rear pylon under the rear rotor blades. The self-sealing fuel tanks are mounted in external fairings on the sides of the fuselage. … Three additional fuel tanks can be carried in the cargo area.

Can helicopters fly upside down?

A few modern helicopters can perform a roll and are hence flying upside down for a few moments but they cannot maintain sustained inverted flight, unlike a fixed wing aircraft. Older machines did not have the power or the rotor technology to make rolls a safe aerobatic option.

How do helicopters go forward?

Only the main rotor is used to move the helicopter up and down, and to make the helicopter tilt forward, backward, left, or right. … By tilting a blade to increase the blade’s angle of attack, the pilot can increase the force of lift that is pushing up on that blade.

How do helicopters change direction?

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.

Can police helicopters see inside your house?

Police Helicopters can see into your home only when looking through a window with the HD color camera. The infrared camera is unable to look through walls, roofs, or structures because it only detects heat given off by an object. It can see if a house, room, or roof is hotter than its surroundings.

Why is it so hard to hover a helicopter?

Then, if you move the cyclic forward the helicopter will start to descend, so you need to raise the collective, which means you need to apply left pedal, and so on. And the inherent instability means that you can’t just keep all controls static so that the helicopter does not move (it’s been tried).

How long can a helicopter hover in the same spot?

Most helicopters hover within “ground effect”. This is defined as a height above ground equivalent to the rotor diameter, that is, if the span of the tip of one rotor to the other is 100 feet, then the helicopter is capable of hovering in ground effect up to 100 feet.
