Study on Flight Performance of Propeller-Driven UAV

Table 2

Flight performance parameters of UAV.

Flight performance	Performance index	Index meaning
Propeller thrust characteristics	Propeller efficiency	The ability of the propeller to transform the output power of the engine into available power
	Available power of the propeller	The final output power of a propeller under a given operating condition
Maneuverability	Maximum climb rate	Maximum vertical velocity of UAV under given operating conditions
	Minimum turning radius	The minimum horizontal turning radius of a UAV under given operating conditions
Flight envelope	Minimum flight speed	Stall speed of UAV at the maximum lift coefficient
	Maximum flight speed	The maximum speed of the UAV under the maximum output power
	Service ceiling	The maximum altitude of the UAV under the maximum output power with a climbing rate of 0.5 m/s
Duration performance	Maximum range	The most distant flight distance of UAV under a given fuel consumption rate
	Maximum endurance	The longest flight duration of UAV under the maximum output power
