HISTORY The minds of early inventors were inspired by a bird and by the rotary principle. Ancient Chinese had a hand spun toy sometimes called a “flying top” that rose upward when it revolved rapidly. It is probable, that the first man to investigate a man lifting helicopter to be Leonardo da Vinci. Leonardo made drawings showing an aircraft with a rotor around the year of 1500.
History cont. Later around the year 1843, Sir George Caley designed many vertical take-off and landing aircraft. His designs were not workable because at that time there were no engines that were both light and powerful enough to drive an air machine that is heavier-than-air. In the end it was Louis Charles Breguet who made the first man carrying helicopter. It only rose about 60 centimetres from the ground for one minute on August 24, 1907.
How does a heliman work? A heliman is an aircraft designed to prevent pollution by using energy generated by heat power. A heliman has a large fuselage (body) that is 17 metres and 85 centimetres long, 4metres and 80 centimetres wide, and three metres in height. It consists of three rotors. Two of which are on each side of the wing underneath the fuselage. The other rotor known as the main rotor is on the top of the fuselage. For long distance travel, there is a kitchen to provide food, and there is a toilet block for males and females.
How a heliman works? cont. Two pilots control a heliman so there is a large cockpit where all the controls are. The controls consist of an instrument console, rudder pedals, cyclic pitch stick (controls lateral motion), a collective pitch lever (controls up and down motion and engine speed), throttle and two pilot’s seats. The engine and fuel are located in the battery compartment where the heat energy battery is stored. A heliman has two aisles with two people on each left and right side sections. There are seven people in the middle section. There are fifty rows for all three sections. Altogether a heliman holds 560 people. 550 passengers and 10 crew.
How does a heliman work? cont. A heliman is powered by heat power, so to get a heliman to take-off land, the battery that is made of heat is turned on. This enables all three rotors to start spinning and lift the aircraft vertically off land. Of course the rotor need to spin considerably fast to lift this large machinery that is heavier-than-air off ground. Unlike take-off where the battery is turned on, to land the battery needs to be reduced to a lower energy supply rate. This will decrease the speed of the engine. The collective pitch will also need to take place by controlling the heliman to the desired landing spot. A heliman can hover motionless in mid-air. This is what makes this unique device to land on any surface. Whilst in air, the cyclic pitch directs a heliman in any direction whether being forwards, backwards, left or right.
How does a heliman fly? Cont. A heliman runs on heat power. Heat is a good fuel to use because it doesn’t pollute the air and it is easy to collect because scientists have found that there is heat everywhere even in Iceland! The way it works is. Firstly, people pump water into the ground through a man made well. The water turns to steam as it becomes warmer by the earth. The steam goes up through a different well where it turns turbines that generate electricity. People then store generated electricity into a battery. After that the battery is placed into the battery compartment inside the heliman. The heliman stops pollution because it doesn’t use petrol. The battery consists of recycled material which makes the heliman fly.
