The largest aircraft
Modern man, living in the age of high technology, really to surprise with something very difficult, and especially the mention of such a vehicle, as the airship does not have any Association with the promotion of the development of science and technology. The majority of inhabitants is of great slowly floats among the clouds the ship from the past, which controls the eccentric pilot in a leather helmet, brown jacket and resemble dragonfly eyes glasses. But what if airships are still in service and professionals they are so perfected that they have become a real breakthrough in the world of flying machines? Actually, it is, and there is now a large air ship hybrid «Airlander-10», whose flaws are minimized and advantages outshine many peers.
The creation of a huge airship with a length of 92 meters was engaged near the town of Cardington, which has subsequently peak of popularity of these devices there are two giant hangar the size of a football field. The sponsor of the project «Airlander-10» made by U.S. authorities, who decided to use it if necessary for military purposes, but the main purpose of the ship – transportation of household goods is carried out within the peaceful commercial exploitation.
The uniqueness of manufactured of the vessel is that during design development, the creators have crossed the aerodynamic characteristics of aircraft and airships to get rid of the shortcomings and those of others and learn from their positive points only. For the construction of a hybrid was attracted by the firm’s sub-contractors about a hundred professionals. After the completion of the key works in the production there are only 20 people, most of whom were consultants.
Shell and volatility
When creating the machine was used high quality polymer materials that have improved such indicators as durability, useful life and the flow of air. The main material of the shell – polymer «Vectran», which is characterized by stability and durability. It’s filled with helium shell, due to the pressure which the ship is kept in the air. Also installed aerodynamic lines that contribute to the volatility of the airship.
The design provides also the presence of rotary engines with propellers, similar to those which are equipped with helicopters. Because of their actions «Airlander-10» may for a long time «hang» in the air and remain motionless. Another feature is the ability even with the engine off to slowly sink to the surface of the earth, allowing you to avoid accidents.
Power and control
The airship is equipped with four turbo-diesel engines, 350 horsepower each. The system control apparatus based on the use of modern advanced technology, which increase efficiency and contribute to the rapid switching from one task to another.
A group of engineers working on the project, already thinking on the creation of more efficient vessel, capacity of which will be five times larger than the existing. The planned introduction of gas-turbine engines and air bags similar to those fitted to some ships. Regarding the power of engines is still being debated.
The maximum weight is 20 tonnes, including cargo. Relative to its size, this number is small, but should take into account other parameters, showing a positive way. So, to stay in the air without interruption «Airlander-10» maybe five days in a row, the fuel consumption is minimal. Tens of thousands of miles he can swim in the air without any additional landing or refueling. Its speed – 150 km/h, Maximum altitude – 6 km above ground level.
The first test of the airship-a hybrid was held in his hometown of Cardington that is located within the County of Bedfordshire, August 8, 2016. The objectives of this flight was to get in the air to a height of 150 meters, fly around the airfield at speeds up to 65 km/h, to stay in the flight for 19 minutes and then make a smooth landing at the designated spot. With all the tasks «Airlander-10» handled without any misfires.
The second flight
The second flight, the perfect 24 August 2016 in close proximity to the capital of great Britain, was less successful. After carrying out the planned activities the ship returned to base and accidentally touched the electric wires, and then collapsed to the ground. Fortunately, the crew remained unharmed, but the airship now requires a thorough repair.
