The aim of this research is to employ a sensitivity study for the total thrust of a ducted twin counter-rotating propeller system design for UAV applications using computational fluid dynamics (CFD). Two factors were investigated: propeller spacing and difference between blades pitch angle. Using discrete values for both factors, 32 designs were analysed and evaluated. The same approach was also used for an equivalent unducted propeller system to access the influence of the duct.

SRI method of planting requires planting the seedlings on the grid which is difficult for the workers who do not normally follow proper spacing in planting and maintain seedling population per hill. To overcome such difficulties, a suitable transplanter should be developed for SRI method of cultivation. There are several self-propelled rice transplanters available commercially, which will reduce labour requirement drastically thereby reducing the cost of cultivation.

This paper deals with transportation technology regarding links between power unit and cargo space. These links can be divided into two groups: rigid and flexible. Rigid link, established between power unit and cargo space, is dominant in maritime and road transport (sea ships and trucks), and occasionally in transport on inland waterways (self – propelled barges). Flexible link is used in the railroad transport (systems with trailers and semi trailers), and in inland waterway transport (push – towing and pulling systems, and combinations of the systems).
