TECHNOLOGY OF MANUFACTURING AND ASSEMBLAGE OF TRANSPORT MACHINERY HELICAL PROPELLERS
The paper reports the consideration of transport machines propeller creation for their motion on land, on water and under water at high speed, with greater load carrying capacity and low energy consumption. The increase of technological potentialities, speed and load carrying capacity of transport machines is achieved by means of manufacturing a propeller as a helical jacket with the possibility of drive shaft rotation. Such propellers are called helical by us, as around their perimeter along the entire length there are formed multistart helical curved surfaces like helical grooves of different forms and dimensions. As a result of the work carried out the designs of helical propellers are offered which novelty is confirmed by patents for invention and their classification in which is a general principle allowing the development of still unknown designs of helical propellers. The original design search of helical propellers was carried out by the methods of descriptive geometry and engineering graphics which allowed forming them around the perimeter with curvilinear or flat elements with overlaps or without them and also with the aid of “Compass-3D” program complex. The technologies and designs of helical propellers ensuring high speed of transport machine motion on land, on water and under water are offered.
