Propellants, Explosives, Pyrotechnics, EarlyView.A high‐performance premixed monopropellant is prepared from hydrocarbon‐filled microcapsules and hydrogen peroxide. This propellant is burned in a strand burner, and the effect of different parameters on the burn rate is evaluated. ABSTRACT A dispersion of hydrocarbon‐fuel‐filled microcapsules in gelled hydrogen peroxide can form a premixed ...

Control System for the Navigation of the Agricultural Robots: A Review
Journal of Field Robotics, EarlyView.ABSTRACT Control systems for the navigation of autonomous agricultural robots—particularly those operating in uneven terrain and in the presence of static or dynamic obstacles—have advanced considerably in recent years. As conventional machinery evolves toward increasingly automated systems, the design of reliable navigation controllers has become ...

Stability assessment of agricultural tractors and self-propelled sprayers
, 2019 Agricultural machines often work on rough terrain and sloping ground so instability and rollover events can easily occur. For agricultural tractors the solution adopted at international level was to provide them with Roll-Over Protective Structures (ROPS). Agricultural machines currently have to comply with the European Community (EC) 2006/42 Directive

CONFORMANCE OF OPERATING POST OF SELF-PROPELLED SPRAYERS
, 2011 The operation of self-propelled sprayers requires considerable physical and mental efforts of operators. The correct layout of controls significantly increases operating efficiency. This study aimed to verify and compare the location of more as well as less frequently used operating commands in five brands of self-propelled sprayers, according to the ...
