Why did we start our investigation? Because of curiosity; The interest to the super light aircraft; To evaluate the correspondence of obtained results to the real winged seed flight parameters.
Слайд 1The Aerodynamics Of A Single-Blade Rotor
The Mathematical Model Of Single-Blade Rotor
Flight
Слайд 2Why did we start our investigation?
Because of curiosity;
The interest to the
super light aircraft;
To evaluate the correspondence of obtained results to the real winged seed flight parameters.
To evaluate the correspondence of obtained results to the real winged seed flight parameters.
Слайд 3The Aim of the work
To investigate the aerodynamics of single blade
rotor (SBR);
To construct its (SBR) mathematical model;
To get acquainted with results of scientific researches in this area;
To solve the equation of motion of SBR: to find the angular velocity of autorotation.
To sophisticate the idea of SBR motion.
To construct its (SBR) mathematical model;
To get acquainted with results of scientific researches in this area;
To solve the equation of motion of SBR: to find the angular velocity of autorotation.
To sophisticate the idea of SBR motion.
Слайд 4We assumed the model of a winged seed aerodynamics and, based
on it, we decided to create the single blade rotor.
Слайд 7MEG-1X
MEG-1X was created by American engineer Eugene Gluhareff in 1955. The
creator of MEG-1X, following the ancient wisdom “the less, the better”, has coherently thrown out all the excessive details, he did not spare even the blades: only one of them stayed with a jet engine, attached to its end.
Слайд 8In USSR the pioneer in creation of single bladed helicopter was
the student of Kharkov Aviation Institute, Yuri Marinchenko. The original version of helicopter was planned as a backpack weighting 30 kg. He developed this idea during a year and, in 1971 the model was established.
Слайд 9AliSport
Nowadays the only firm, Alisport, creates the full-size aircraft with single
blade rotor.
They created the famous one-bladed gliders.
They created the famous one-bladed gliders.
