Helicopters
A helicopter is an aircraft which is propelled and lifted in the air by one or more large horizontal rotors. Focke-Wulf Fw 61 was the first operational helicopter manufactured by Focke-Achgelis in 1936.

Can a car engine be used for a helicopter?
It is possible to use an automobile engine to power a helicopter, but the thing better be light (have an aluminum block and heads) and have a high horsepower to weight ratio. But it can't be a hot rod engine either. It absolutely must be set up to run extremely reliably or you'll be autorotating down every week. A light plane or gyro-copter may be easier to build from scratch, but you may have figured that out already.
The Lycoming engines (O-235, O-290, O-320, O-360,...) used in light aircraft have been adapted for use in a number of home brew or kit rotorcraft. A lot of two-seater helicopters are built using them. But they cost. A more modest power plant can be used to power up a single-seater. You can pay $3K to $4K just for a Lycoming core (the whole engine, but outside its hours and needing to be rebuilt).
Are you going to design the thing and build it from scratch? Or use a plan to construct it? Plans aren't free, but they have a singular advantage - they have been proven, have been engineered to work. Plus, critical parts can be purchased instead of built (machined). If you plan to fly this thing, what's your life worth?
Have you looked at the Adams-Wilson Choppy plans? (The A/W-95 is the current run, if memory serves.) They use about the smallest airframe and a modest power plant to lift one person (about 250 pounds) clear of the ground. These have been built and flown so they're relatively safe. The whole thing is doable at home. (Which is why it was designed.) Plans cost about a hundred bucks.
There are mini helicopters and gyrocopters that have motorcycle engines adapted for use to power them up. Hit the www and check it out. If you're not already surfing the net for info, you should be. What you waitin' on?
There are going to be severe limits on what you can do unless you have a machine shop. The swash plate and pitch linkage is not something that can be "welded up" from scrap. It has to be machined. The main rotor hub must be adequate. And what about the tail rotor drive mechanism? You lose a tail rotor and you won't be autorotating the vehicle in. (Your loss of control will yield a high probably of serious injury or death, and probably the latter.)
And if you haven't looked into FAA regs regarding home builts, you need to. These aren't local cops; they're Feds, and they'll kick your butt for fooling around with uncleared (uncertified) aircraft. Any flying machine can fall onto a citizen or a house or other structure. It can be much worse than a car crash. You don't want to be crashing or even autorotating into someone's back yard and a kid's birthday party there, do you? A flying machine puts people at risk like no vehicle can. You been warned, ait?

What are the chances of dying in a helicopter crash?
If you are flying over a dense forest, over deep water, and over high snow, and the helicopter suddenly crashes you have a pretty chance of getting out of the helicopter.
Ian Thorpe - an Australian swimmer - was sometimes called thorpedo.
What is the difference between a Black Hawk and a Pave Hawk?
The UH-60 'Black Hawk' Helicopter was derived from the original Sikorsky S-70 model, and put into service with with the US Army beginning in 1979. It was purchased by the Army as an eventual replacement for the UH-1 'Iroquois', nicknamed 'Huey'. The UH-60 Black Hawks carried greater loads, including more troops, and had greater range. There a great many variants of the Sikorsky S-70 / UH-60, including variants used by the military forces of many nations. There are also US Navy variants of the S-70/UH-60 called the SH-60 'Seahawk'. An army variant of the original UH-60 is an MH-60 'stealth helicopter' version, modified to reduce radar signature. Two of these were used in the special operation by US Navy Seals to get Osama bin Laden. As for the Pave Hawk, this was another variant, the HH-60. This variant was fitted with various special electronic features to aid in search and rescue missions, as well as insertion and extraction of special operations personnel.
How much does a gallon of aviation fuel weight?
Av gas (100 LL) weighs the same as automotive fuel....6 lbs/gal.
What is the acceleration of a Chinook helicopter?
Acceleration of a Chinook is relatively slow. Load carrying, not speed, is it's forte.
How do you fly wac helicopters in garrys mod?
To fly the WAC helicopter in Garry's Mod, use R to start the rotors, Q to throttle up, and Z to throttle down. The helicopter can be directed with the mouse.
May be you should try to check yourself about the history of the car. Have you tried any websites?
Are helicopters faster than formula 1 cars?
Some are, yes, but not all of them. Military attack helicopters tend to be the fastest.
The average speed of a formula 1 car is 230 MPH.
The average speed of an Apache attack helicopter is 365 MPH.
What kind of helicopter is Marine One?
It is the VH-3D Sea King but is scheduled for replacement in the near future.
What is better a fighter jet or helicopter?
That's like asking if a shovel is better than a bandsaw, it all depends on what the pilot is asked to do. A helicopter can land just about anywhere, but it can't hunt down another aeroplane.
Can a plane fly without a rudder?
no . The correct answer is YES. It flies better with a rudder which is used to corrdinate a banked turn. However most conventional planes can turn by banking the airplane. In WWII many bombers returned from missions with most or all of the rudder being shot off and till landed successfully.
- - - - -
The B-2 bomber has no rudder, and it flies fine.

What fuel does Black Hawk use?
Black Hawks use jet fuel. You can use any of these fuels in one:
Jet-A
Jet-A1
JP-4
JP-5
JP-8
In a real emergency when aviation fuel wasn't available, you could run kerosene or diesel in it, but that's not something you do if you don't absolutely have to.

Do helicopters need gas or fuel to fly?
Of course. Standard piston engines are fueled with a good quality gasoline, and the jet turbines run on jet fuel, which is most likely a kerosene-based product.
What is the decibel level of a Sikorsky CH-3C helicopter?
The vortex noise decibel level of Sikorsky CH 3C helicopter is calculated in different parameters of the five rotatory blade revolutions per minute (rpm),thrust,sound pressure level (SPL),angular velocity radians per second, etc.
At 183 rpm at 13400 pound thrust it is 78 db,for 20,500 pound trust it is 82 db. Similarly at 213 rpm rotor speed at 20000 pound thrust the noise level is 83 db.

Early helicopters all used piston engines up to the 1960's . Now most helicopters use jets, except for a few small civilian helicopters. The jets are connected to a very strong and complex transmission which turns the main and tail rotors.
