PROSPECTS FOR THE APPLICATION OF ENGINES OF NON-TRADITIONAL DESIGNS

Abstract

One of the topical directions of increasing the fuel efficiency, maneuverability, power reserve and multi-fuel capability
of military equipment is considered. The existing internal combustion engines today have sufficient technical solutions that
provide high fuel-economic and environmental performance of the engine's working process. Along with this, such engines
require the solution of the following problems: improving weight and size indicators, reducing cost and simplifying the
design, increasing reliability, and the like. The main tasks of vehicles also include reducing the level of engine vibration. This
task is especially relevant for engines that are installed on military equipment. To solve this problem, a connecting rodless
engine with a crank-rocker power mechanism was considered. New technical solutions are proposed that comprehensively
solve the problem of creating a new connecting rodless engine with a variable compression ratio for military equipment. The
principle of operation of a connecting rodless engine with a crank-rocker mechanism is considered, the results of theoretical
and experimental studies of a connecting rodless engine are given. Its advantages and disadvantages are analyzed.
Recommendations are given on the use of an engine with a crank-rocker mechanism in military equipment. The complete
balance of the proposed engine ensures a low level of vibration and noise of the power plant for any purpose. Such engines
were in great demand today for unmanned aerial vehicles, where the absence of vibrations plays an important role for the
normal operation of sensitive equipment. The rockerless engine with a crank-rocker mechanism can be used in hybrid
quadrocopters for automatic monitoring, since there is no vibration in the engine, as well as for cargo delivery and security
control of technical facilities. Such a quadrocopter–type unmanned aerial vehicle is distinguished by the use of two types of
engines: a spinless internal combustion engine – to create lift and generate electricity, and a low-power electric motor - for
flight control. This design allows for a large load capacity and flight duration, unlike quadrocopters with electric motors.
