Iranian scientists built vertical take-off and landing (VTOL) aircraft capable of using non-metric cameras to prepare large-scale maps.
A faculty member of Iranian Khajeh Nasir Toosi University of Technology, Masoud Varshowsaz who has presented the systems plan said a quadrotor was built for mapping, ISNA reported.
Quadrotor is not a new system and has been already built and used for watching weather, but has not been used in Iran for mapping.
He said aerial photography now carried out by large aircrafts costs much, they are economical in large projects, but cannot be used in small ones.
Toosi added that the newly-built aircraft can carry out aerial photography in small projects and enjoys considerable flexibility.
It is produced with low cost and can be used in mountainous areas and bad weather.
He added the aircraft can prepare large-scale maps with the precision of 5-10 centimeters.
A vertical take-off and landing (VTOL) aircraft is one that can hover, take off and land vertically. This classification includes fixed-wing aircraft as well as helicopters and other aircraft with powered rotors, such as cyclogyros/cyclocopters and tiltrotors.
Some VTOL aircraft can operate in other modes as well, such as CTOL (conventional take-off and landing), STOL (short take-off and landing), and/or STOVL (short take-off and vertical landing). Others, such as some helicopters, can only operate by VTOL, due to the aircraft lacking landing gear that can handle horizontal motion. VTOL is a subset of V/STOL (vertical and/or short take-off and landing).
The helicopters form of VTOL allows it to take off and land vertically, hover, fly forwards, backwards and laterally. These attributes allow helicopters to be used in congested or isolated areas where fixed-wing aircraft would usually not be able to take off or land.
