Drone Current Consumption Calculator

This calculator estimates the current consumption of your drone based on its weight, propeller configuration, and flight mode. The calculations use a combination of theoretical models and empirical data to provide realistic estimates.

• Basic Physics: The power needed to keep a drone airborne is directly related to its weight, air density, and efficiency.
• Flight Modes: Different flying styles require different amounts of power. Hovering is our baseline, while acrobatic flying can use up to 50% more power.
• System Efficiency: Motors, ESCs, and propellers all impact how efficiently electrical energy is converted to thrust.
• Battery Capacity: The estimated flight time is calculated using 80% of your battery's capacity as a safety margin, as LiPo batteries should not be discharged below 20%.

where power P is derived from thrust requirements and velocity. For hovering, we use the theoretical minimum power formula. I = P/V where v is air velocity, T is thrust, and η is system efficiency. For hovering conditions, we use:

Propeller size and pitch also affect efficiency. A larger propeller diameter typically provides more efficient thrust, while the pitch-to-diameter ratio affects both thrust and efficiency.
