MALE UAV design of an increased reliability level

This study seeks to present the initial requirements for medium altitude long endurance (MALE) UAV design of an increased reliability.

Shows and describes the successive design phases of PW‐103 MALE UAV.

The analysis of the performances of the PW‐103 UAV, powered by either a main or an auxiliary engine, demonstrated that auxiliary power unit improved flight safety significantly.

Successive MALE UAV configurations developed in the design process were aerodynamically more efficient than their predecessors.
