Tyto Robotics illustrates the process of connecting analog sensors to Flight Stands, showcasing practical applications that emphasize the advantages of additional sensors, along with potential challenges encountered during testing.
A thrust stand is crucial for evaluating the thrust, torque, RPM, and efficiency of your propulsion system. By integrating sensors into your testing framework, you can achieve a higher level of optimization that enhances overall performance.
In the realm of unmanned systems, gathering data from external sensors is often fraught with difficulties. To tackle these challenges, Tyto Robotics has introduced a new software feature named “Input Transformations.” This functionality enables the connection of external analog sensors to all Flight Stand models, allowing for seamless integration of sensor data with propulsion metrics.
Integrating Sensors with Flight Stands
Elevate your unmanned aerial vehicle (UAV) testing by adding external sensors to your Flight Stand configuration. This guide will demonstrate how to utilize a sound sensor to optimize propeller noise levels, which is essential for achieving quieter flight operations.
Measuring Sound Levels
We will assess the decibel output from a propulsion system (Xoar 26-inch propeller paired with an AXI 8110 motor) using a SEN0232 sound meter connected to the Flight Stand 15 pro. This device operates on a 5V input and measures sound levels in the range of 30-130 dBA.
steps for Connection:
- Ensure the Flight Stand is connected via USB
- Open the Input Transformations tab
- Create a new transformation
- Label the sensor (e.g., “sound Sensor”)
- Select the unit type or input “dB”
- Assign voltage input to variable “a”
- Enter the conversion formula (e.g., a * 50)
- Set system limits according to specifications
- Save the configuration
- Go to Powertrain Mappings
- Select “Transformations – Sound sensor”
- Commence testing as usual
Sensor data will be included in the exported CSV files. For instance, at a throttle of 1500μs and 1099.45 RPM, the system produced a noise level of 76.18 dB.
