Propulsion Performance

This module contains static (ground test) performance data and overall system efficiency for the motor-propeller combination.

Static Performance (Full Throttle)

Parameter	Unit	Description
static_thrust_max	g	Total thrust produced at maximum throttle.
static_power_max	W	Total power consumed at maximum throttle.
static_current_max	A	Total current drawn at maximum throttle.
static_efficiency	g/W	Thrust produced per unit power (efficiency) at full throttle.

System Metrics

Parameter	Unit	Description
thrust_to_weight	-	Thrust / Weight ratio. Values >1 indicate unlimited vertical climb capability.
pitch_speed	m/s	Theoretical air speed based on propeller pitch. typically limits the maximum flight speed.

Performance Curves

The curves object contains arrays representing performance across the throttle/RPM range.

Parameter	Unit	Description
rpm	RPM	Motor revolution per minute values (X-axis).
thrust	g	Thrust at the corresponding RPM.
power	W	Power consumption at the corresponding RPM.
current	A	Current draw at the corresponding RPM.
efficiency	g/W	Efficiency at the corresponding RPM.
