the SOH-1 or Samu-Orosz-Hadhazi was a Hungarian Helicopter of 1954,page 128.
Here is some info translated from http://100hires.hu/cikkek/samu-orosz-hadhazi-soh-1-helikopter-1959
The world's first helicopter to be considered truly successful designers in the German Focke-Wulf was made at the FW-61 will be added. The machine - although a significant addition to the pilot was not able to lift a payload - from 1937 all broke the previous record for free-flying helicopters class. In May 1937, the first landing autorotációs also implemented it. Focke Achgelis later partnered developed the first type of series is produced in the world, at 223 Wood
The advanced helicopters in terms of aerodynamic and structural design of the most complex structures, they also include assets are flying today, you want a thorough understanding of the entire operation, engineering-level technical skills. It is no coincidence that the aircraft can only see the history of the really useful for rotary wing aircraft during the last decades - sufficient knowledge and experience is only thirty - forty years gyűlhettek be a significant part in the development of fixed-wing machines.
Heavier than air flight vehicles, aircraft fundamental criterion to lift necessary for its survival is established in what way. In the case of aircraft airfoil with a special shape is defined ( "drop shape") built wings formed bearing the weight of the machine buoyancy. As the formation of the air force needed to move the wing some otherwise be established with a speed of the air.
Our helicopters can use this law. Same as aircraft wing sections of profiled rotor blades turn is reached by rotation about the rotor axis to the adequate megfúvási speed, "produced" buoyancy, i.e. stationary relative to the ground position of the helicopter rotor can be generated weight of the structure overcoming air force.
The helicopter's engineers with at least one rotor (foreign words, rotor, main rotor) and an auxiliary tail rotor, or more - common or separate axes placed - főrotort used.
The MTI news release says:
"Pilot helicopter airplane built by the University of Technology Department of the laboratory. The three designers: Hadházi Daniel, assistant professor of the department, Russia Eugene, Budapest Petroleum Equipment Factory engineers and Sam Bela, the engineer Japhia. With regard to the motor rotor system of two patents they have been registered with the designers. The pre-flight measurements began in Budaörs airport. "
The designers have seen to-date with the cyclic controlled metal-built helicopter rotor háromlapátú experiments after preparatory work beginning in 1954 to the Institute of Experimental Dunakeszi-Alag-i. A helicopter rotor head structure (Hadházi Daniel patented) an effective stabilizing system and government forces appreciably reported a significant step in the construction of helicopters, which triggered international interest as well.
The machine is the first test of rolling in the air because of a test pilot, Imre Reaper early for his activities, but to crush damaged. After the injury in connection with the helicopter-building Knebel study was conducted, and more with the machine is not airborne. One - involved in the construction of the machine - professional Link (hardwood) William recalled that the tool and documentation of Soviet specialists removed. One of the aluminum models and helicopters for the SOH-1 helicopter rotor blade was riveted technical university studies in the Hungarian Transport Museum's collection.

Nice Info Aschiro
Wonky as pants translation aschiro! Barely has much to offer for the type being discussed either and when it does its almost useless because of the botched deciphering. :P
