Opis:
The preliminary design of a multipurpose engineering machine on the wheeled chassis was presented in the paper. The machine meets a series of specific requirements such as: off-road prowess, ability of movement with high speed on hard-surface roads, limited weight and dimensions at the maintaining of great hoisting capacity. These requirements were adjusted to the present character of warfare and that is why the machine construction deviates from classic working machines being used in the civil sector. The meeting of defined requirements required the development of innovative methods. The solution aiming at the increasing the stability of the machine by the application of using a sliding drive unit was described. As a result of that, the increased capacity and efficiency of mined materials were obtained. Additionally, the system of two telescopic arms was applied, so that the efficiency was improved by the shortening of machine working cycles and it is possible to change the length of arms as well as both telescopic arms were placed on the rotating body achieving in such a manner the big workspace for arms. The 3D model of a multipurpose engineering machine and model with rear mounted drive unit and raised and extended arms are presented in the paper.

Opis:
In the article there was presented a quality assessment of parameters selection of bypass turbine engine for a multipurpose aircraft. It was assumed that the assessment criterion results from the energy-consumption of a flight. The criteria of energy-consumption range were defined as the relation of sum ofenergy supplied to the aircraft on the driven stages to the distance during a mission. The second criterion of unitary energy-consumption is defined as the relation of the movement energy-consumption to the product of the aircraft mass and the route during the elementary stage of the flight. With the use of the already worked out models of the power unit (bypass turbine engine with jet mixer and afterburner) of an aircraft (already known mass and aerodynamic characteristics) there were determined the ranges of thrust which are indispensable for a flight and available for the engine at each stage of the mission: take off, climb, subsonic and supersonic flight and turn with different overload factor. On the example of three chosen aircraft missions (Lo-Lo-Lo, Hi-Lo-Hi and Hi-Hi-Hi) the models of mission energy-consumption were developed. For the accepted change ranges of the comparative cycle parameters of the turbine engine the run of energy-consumption was tested. It was stated that for the assumed data the most energy-consuming mission is Lo-Lo-Lo, wherefore the increase of the compression and the rate of bypass reduces the energy-consumption of the mission.
