Helicopters

Planes fly by generating lift from the wings as they move through the air. This lift is created by the shape of the wings and the speed at which the plane is moving. Engines provide the necessary thrust to propel the plane forward.

Actually, a helicopter can fly upside down but not for long.If you go to... http://www.guardian.co.UK/notesandqueries/query/0,,-186989,00.htmlYou can get answer to why I say they can fly upside down. They can only fly upside down for a certain amount of time though.My reference is ^. I am NOT playgerizing.The reason is due to the design of the rotor blades and the grips that hold them and the mast. It is how the parts were designed to carry loads. Most Mast and Blade designs are build to carry a load UNDER it but it is not rigid enough to invert it so the load is above it.Most vintage Bell Helicotpers had teetering rotors and was limited to about 60 degree banks because the rotor blade would bang against the mast. In the 1980's they had some accidents involving "mast bumping" and they had to redesign the rotor system to include bumper pads or stiff springs to absorb the shock of the blade hitting the mast.However, most times that helicopters are flown upside-down they are flying such that the G-forces is still loading the rotor blades in the same direction. They can do a Loop or a Split-S and the momemtum of the helicopter keeps the rotor blades loaded in a positive force. They very seldom fly inverted in level flight so the load on the rotor is Negative.

The place where the airplane balances. It can vary, because fuel, passengers, cargo and so forth can be put in various places.

If the center of gravity is too far from the ideal location (out of limits) the aircraft will not handle properly, and may not fly at all. Worse, it may get into the air and then become uncontrollable. Failure to properly calculate and adjust CG has killed many pilots and their passengers. The aircraft has to "Balance" all the forces of Lift and Weight. The tail control surfaces (on typical aircraft) are used to balance the aircraft a small amount. The Center of Lift is usually located about 1/4 the width of the wing airfoil, measured from the nose of the wing. The Center of Gravity for the weight of the entire airplane and its contents should be close to this same location.

The lead is emitted by the car exhaust as a gas which can be absorbed in the bodies of people who breathe the gas. It accumulates in the body as the body has no mechanism to deal with it and affects the brain, reducing IQ.

Answer That is easy and it is difficult to explain. Each of the helicopter blades act as a wing and produce Lift. The blades have control inputs that rotate it so its angle increases and this increases lift. When the pilot pulls UP on the Collective Controls, this increases the pitch of all the blades at once so all begin to lift together. The helicopter will rise vertically. In order for the helicopter to fly forward, the Cyclic Controls increases the pitch on each blade as it reaches a specific point in its rotation around the Mast. This pulls the aircraft forward. Think of it as rowing a boat by swinging your paddle around your body but only dipping it into the water at one point.

The "advancing blade" of a helicopter refers to the side of the rotor which moves forward in relation to the fuselage. As each rotor blade makes a full circle around the center, on one side of the swing, it moves forward, and on the opposite side it is moving towards the rear of the helicopter.

When the helicopter is moving forward in air, the rotor blades on the advancing side are moving at a higher airspeed than the rotor blades elsewhere. Rotor speed + aircrafts forward airspeed. This results in slightly more lift on that side. Conversely the exact opposite is happening on the other side where you get Rotor speed - aircraft forward airspeed. This creates a tendency for helicopters to want to roll at high airspeed.

This is one of the many odd tendencies of rotor aircraft that pilots are constantly adjusting to balance out.

The source of lift force from the rotor (Rotation of two objects 'blade' creates a lifting force) blades allows the helicopter to stay in one area for extended periods of time. Each rotor blade, whether it is 2 or 7, has the ability to change pitch. This means the blade can rotate so that the nose or leading edge can tilt down or up. If it pitches up, the lift of the blade increases. Collective Controls As the blades rotate it produces lift. The pilot inputs controls that increases the pitch on all the blades at once. All the blades pitch up and produce more lift, so the helicopter rises. Cyclic Controls The pitch of the blades can also be controlled so that the blade pitches UP when it is on one side of the helicopter and pitches DOWN when it is on the other side. As the advancing blade is moving from rear to front, it decreases it Lift. Then as the blade moves to other side, it increases its Lift and pushes the helo through the air. In a simply explanation, this is what causes the helicopter to fly forward. Think of it like someone paddling a canoe. On many helicopters, the input is accomplished through the controls of the Swashplate. Custermen - Worked 11 years at Bell Helicopter.

A helicopter is able to fly because of the lifting effect of its main rotor.

The rotor blades of a helicopter act in the same manner as the wings of a plane, creating lift by forcing air above and below a curved airfoil. The air moves faster over the top of the blade, reducing the pressure there. The air below pushes upward with greater pressure, lifting the rotor and the attached frame and cabin. At the same time, the blades can be angled in any direction, allowing it to move in any direction by using the blades like the propellers on an airplane. Jet helicopters also generate some forward speed from their turbine exhaust.

The main rotor is the set of blades on the top of the craft, driven by the engine (piston, jet turbine, etc.). By turning the blades, which are airfoils and like a narrow "wing" in shape, we move them through the air. And by "tipping" the leading edge of the blade up (increasing the pitch) as it moves, the blade will have a positive angle of attack. It will bite into the air and force that air down. This forces the blades up, and the rotor will provide lift. Lift causes the craft to defy gravity.

The torque (rotational motion) of a single rotor blade will have to be offset, and the tail rotor does this. Additionally, the tail rotor (or air turbine in the NOTAR helicopter) will also allow the craft to be turned and "pointed" in another direction. The pedals control the tail rotor or air turbine. By pushing the stick to the side (and adding a bit more pitch with the cyclic), the blades can be controlled to allow a bit more lift on one side to tip or bank the chopper and turn it. (A bit more pitch is added to offset the slight loss of lift.) The pedals will also be used in conjunction with the stick. By pushing the stick left, the blades will have a bit more pitch as they come around on the right side and a bit less as they come around on the left side. This will bank and turn the helicopter.

Pushing the stick forward causes more pitch to the blades as they come around the back of the circle they make around the craft. This lifts the back of the craft. And it will make for a bit less pitch in the front for a bit less lift in front. This tips the craft forward. Often when we see a helicopter take off, it rises a bit, tips forward (now that the rotors will clear the ground), and accelerates forward as it continues to rise. The pilot has pulled up on the collective (to increase the pitch of the main rotor blades). That provided lift. He also has to push forward on the cyclic to tip the helicopter forward to begin to gather forward airspeed.

A helicopter can take off and land vertically (straight up and down). It can fly in any direction, even sideways and backwards. It can also hover or hang in the air above a given place.

A helicopter gets its power from rotors or blades. When its rotors are spinning, a helicopter doesn't look much like an airplane. But the rotor blades have an airfoil shape like the wings of an airplane. So as the rotors turn, air flows more quickly over the tops of the blades than it does below. This creates enough lift for flight.

Additionally, helicopters avoid areas close to storms. The reason is that the helicopter requires a careful balance of the air supporting it. Downdrafts or turbulent winds can drastically affect control of the helicopter.

Because they are such complex machines.

Helicopters must have all the same switches and controls any airplane has, plus the fact that most modern helicopters have 1 or 2 turbine engines puts them at the same level of complexity as a small jet airplane. Helicopters also must give the pilot very high visibility in a wider viewing range due to the way they are used, this results in a much larger windscreen, and much less room for buttons & switches.

In reality, helicopters have approximately the same number of buttons and switches as an airplane of equivalent size, but they must be crammed into a smaller space to accommodate the larger windscreen.

Lynx - The World's Fastest Helicopter 20 Years On 11/08/2006 The 11th August marks the 20th anniversary of the Westland Lynx helicopter setting a new world helicopter speed record of 249.1 mph (400.87 kph). Although other attempts have been made, 20 years on Lynx retains the title as the world's fastest helicopter.

The time it takes to travel 300 miles by helicopter depends on the helicopter's cruising speed and any external factors like wind or weather. Here's how to estimate the travel time:

1. Find the helicopter's cruising speed:

Cruising speeds for helicopters can vary widely depending on the model and size. Some common ranges are:

Light helicopters: 100-140 mph (160-225 km/h)

Medium helicopters: 140-180 mph (225-290 km/h)

Heavy helicopters: 160-200 mph (257-322 km/h)

Let's assume an average cruising speed of 150 mph for this example.

2. Calculate the travel time:

Use the formula:

Travel time (hours) = Distance (miles) / Cruising speed (mph)

In this case:

Travel time = 300 miles / 150 mph = 2 hours

Therefore, it would take around 2 hours for a helicopter with a cruising speed of 150 mph to travel 300 miles.

3. Consider external factors:

Remember, this is just an estimate. Factors like:

Wind: Strong headwinds can significantly slow down the helicopter, while tailwinds can speed it up.

Weather: Severe weather conditions like storms or fog may require diversions or delays.

Fuel stops: Depending on the helicopter's range and the distance, there might be a need for refueling stops, which adds to the travel time.

If you have specific information about the helicopter and the route, you can get a more accurate estimate by considering these factors.

In the Military, it's a great job! (We're the only branch of the service that sends the Officers out "in harms way"HA)

Seriously though, if you want to be an aircraft mechanic, you should seriously consider joining the military, I joined the Air Force in 1965 & later spent 23 years in Germany working for NATO on the AWACS aeroplanes, I don't regret a moment of it.

If you want a real challenge, join the Navy, those guys do the same job as I did, but under much more difficult circumstances.

In civilian life it's unfortunately about getting the most out of you for the least amount of pay & benefits.

But if you love aeroplanes (engines in my case) Go for it!

50,000 to 100,000 dollars annually.

It is around $50,300. That is how much you would make in a year.

This really depends on the type of job that the pilot is doing. Helicopter pilots are used for such a wide variety of jobs but the average salary ranges from $45,000 to $90,000. Some jobs may even pay less while others have the potential to pay higher. There are so many different jobs out there for helicopter pilots, it is a hard question to answer without being more specific.

Fortunately for aspiring and existing pilots alike, the helicopter industry is on the grow. Over the next several years, it is expected that the majority of experienced pilots currently in the industry will begin to retire as many of them had learned to fly during the Vietnam War. This will open many more doors for those that are entering this competitive job market.

considering that in horseback riding you are sitting on a 1600 pound animal with a mind of its own, im thinking compared to boxing, horseback riding is far more dangerous. im not sure what the statistics are for boxing but in horseback riding, over 100,000 people are mildly to seriously injured a year and over 20 die a year from it. I hope this answers your question :)

But then again, horses don't intentionally try to hurt you. In boxing, the entire point of it is to hurt the competitor.

name of the animal which look a helicopter

The Hummingbird best meets that criteria, it can even go into reverse, but it can't keep it up forever.

makeing propellers takes years of prctace and buckets of skill. i recomend you buy one. thay are no more than $3 for a normal sized ones

The first toy helicopters were made between the 12th and 14th centuries, they were made as string-pulled toys for children. The creators of the toys are unknown, mostly because the only thing that supports this theory are manuscripts and paintings from that time.
