This tool will accurately estimate your PX4 flight time based on your specific input parameters.
PX4 Estimator Calculator
This calculator estimates the hover time of a PX4 based VTOL (Vertical Take-Off and Landing) vehicle based on various parameters.
How to Use
Fill in the respective fields:
- Vehicle Weight: The total weight of your vehicle in grams.
- Battery Capacity: The battery capacity in milliamp hours (mAh).
- Motor Power: The power of each motor in watts (W).
- Number of Motors: Total number of motors on your vehicle.
- Propeller Diameter: Diameter of the propellers in inches.
- Drag Coefficient: A numerical factor that quantifies the drag or resistance of an object in a fluid environment.
- Air Density: Density of the air in kilogram per cubic meter (kg/m³). Default is 1.225 kg/m³.
- Flight Speed: Desired flight speed in meters per second (m/s).
How it Calculates
The calculator takes the inputs provided and calculates the total thrust generated by all the motors combined, estimates the power required to hover, and then calculates the approximate hover time based on the battery capacity. It also calculates the drag force based on the specified speed and propeller area and adjusts the hover time considering the power loss due to drag.
Limitations
This calculator provides an approximation and is based on simplified models:
- Assumes perfect efficiency in power transmission and motor operation.
- Does not account for power system losses, variability in environmental conditions, and motor or propeller efficiency losses.
- The drag model used is simplified and may not be accurate for all vehicle designs.
