   <dim:field mdschema="dc" element="description" qualifier="abstract" lang="sv">The propulsive system is an integral part of any aerial vehicle because it is responsible&#xd;
for producing thrust, which in turn is what allows the vehicle to move through&#xd;
the air. This project investigates and implements a propulsive system to a search&#xd;
and rescue drone aircraft by developing a selection and combination of propellers&#xd;
and motors that will best serve for a given mission. The process for selecting motors&#xd;
and propellers is done by comparing existing products on the market with each&#xd;
other and examining their torque- and efficiency matching. Only a few of the top&#xd;
candidates are selected for further investigation with a testing rig in a wind tunnel,&#xd;
which in turn results in a few suitable combinations of motors and propellers for&#xd;
the dedicated mission and aerodynamic loads. From these results suggestions are&#xd;
made for how the propellers can be modified for a better fit for this specific application.&#xd;
Interesting follow-up projects could include further research by developing&#xd;
new propellers specifically for the application. Additionally, interesting follow-up&#xd;
projects could include further investigation of what kind of motor is optimal, and&#xd;
what batteries can be used and implemented into the drone aircraft.</dim:field>
