The paper clip is attached in order to give your helicopter a little weight. You will be folding the ends of the long dimension of your original index card. Fold one side first and then flip the paper over so you can fold the other side.Once both sides are folded, open them both up halfway. These folds have now formed the wings of your helicopter.

There are several ways of solving this dilemma. You can have two rotors that spin in opposite directions, as in the Chinook, and more recently, designers have experimented with blowing air out of ducts onto the tail boom. But the most common method of preventing the fuselage from spinning uncontrollably is to have a tail rotor.

Turbine Helicopter Engines

So students learn to land on grass first since this is very much easier than landing on asphalt or tarmac. When landing on a hard surface, you have to hover lower and lower, and somehow push through the ground cushion, while not forcing the helicopter onto the ground. It’s not as difficult as it sounds, or as some students think, but it does take a fair amount of skill and finesse.

Norm St. Peter and his wife use their float-equipped Hummingbird to fly from Florida to northern Maine, where they fish remote lakes. A great read with a lot of useful information for the homebuilt helicopter experimenter. Be prepared with a pre-study helicopter and general aviation pilot theory course!

Tail Rotor Drift And Tail Rotor Roll

RotorWay runs its flight school out of Stellar Airpark in Chandler, Arizona, in three sets, or phases, of classes. Phase 1 is mainly for hover practice, which alternates with school on documentation, maintenance, and rigging. According to Robin Wactler, director of the flight school, the best time to come for Phase 1 training is near the end of construction, but before the main rotor is complete. It is important to note that many still challenge the use of non-aircraft turbine being used in higher duty cycles such as for helicopters. On the plus side, these concerns are gradually being answered with increasing reliable flight hours gained with the many in service today in both small helicopters and fixed wing aircraft. The fixed wing community have done much for proving the rotarys viability, especially in the Vans RV type homebuilt aircraft.

So are helicopters harder to fly than an airplane? Airplanes are easier to fly as they are an aerodynamically stable aircraft which means they want to fly. Helicopters are an aerodynamically unstable aircraft which means they do not want to fly. The best way to test any homemade helicopter is under tethered restraint.

Diesel Helicopter Engines

They can choose to ship whatever engine suits their fancy, or can leave the choice to the buyer, who could use a rotary engine from a Mazda RX-7 if he could adapt the power train. Since the FAA does not certify unassembled kit helicopter models as airworthy, it offers no opinion on such matters. On the other hand, in case of mishap, the customer’s number-one legal target is himself, as manufacturer and chief mechanic. Fold the top flaps you made when you cut your paper almost halfway down lengthwise. They should both be folded down but in opposite directions, so that there is one flap on either side of the paper.Once you have folded and creased them, open these flaps up halfway. They have now formed the wings of your helicopter.

This helicopter flight simulator has it all for hours of fun and beneficial pre-pilot training. Attach the paperclip to the bottom of your helicopter. It should go over where you folded the length of your index card in half.

Once you have creased it, unfold the paper and lay it flat. HOMER BELL IS A HOSPITABLE soybean farmer who moonlights as a traveling troubleshooter for kit-helicopter owners; they know him by first name rather than last. Since Bell doesn’t hold an airframe-and-powerplant license, his official role is more mentor than mechanic. It's a neat idea for a popsicle/craft stick project. Below is a supporting YouTube video of this particular homemade helicopter being tested under restraint of tethers. Make sure the paper is not used, messed up, or crinkled.

When the rotor blades start to spin, the air flowing over them produces lift, just as when the wings of an airplane start to move. In the case of a helicopter, this is usually known as total rotor thrust . The direction and magnitude of this can be altered in order to control the helicopter.

Acceleration causes a‘ flap back’, which is a special case of flapping to equality. As the pilot moves the cyclic forward, the rotor disc tilts forward and downwards, and the helicopter accelerates. As it does this, the advancing blade flaps up, and the retreating blade flaps down, as explained. However, the advancing blade reaches its highest point as it arrives at the front of the helicopter, and the retreating blade gets to its lowest point at the back. Thus acceleration stops, as the disc has flapped back to its original position. So if the pilot wants to increase speed, he has to keep moving the cyclic forward continually to prevent this – or as any instructor will constantly tell him – “push through flap back”.

The helicopter’s skids are not designed for this – you must land vertically – so this can be a problem, particularly for inexperienced pilots. Suppose the pilot is in a steady hover in a ten-knot wind and wants to leave the airfield. All he has to do is move the cyclic forward to tilt the rotor disc the way he wants to go, raise the collective so he doesn’t descend, and correct the resulting yaw with the pedals, doesn’t he?

A refurbished Solar T62 gas turbine once used in generators is the standard engine, accounting for a quarter of the kit’s $39,800 price. Its power section spins at 62,000 rpm, more than 1,000 times a second. Gearboxes bring this down by a factor of 20 to suit the tail rotor, and still further for the main rotor. Though the Solar is rated for 160 shaft horsepower, Eagle has cut fuel flow, holding it to 90 shaft hp for longer life. When all checks are done and forms completed, the customer finds that he or she is the manufacturer of a new aircraft, as well as its mechanic, notwithstanding the lack of an airframe-and-powerplant license. On one hand, the sellers of such kits can be agile and adaptive, which helps keep production costs low.

Now, since the force causing the fuselage to want to turn is actually acting along the whole length of the helicopter, what we really need is two small rotors to provide a correcting force at either end of the fuselage. But in practice, this would be extremely complicated to design, so we settle for a single force of double the required magnitude at the rear of the helicopter. This effectively stops the rotation, but now there is a resultant side force moving the helicopter to the right. There have been a few non-starters as the development costs of any engine is excessivly expensive.
