Thrust Stand Comparison: Tyto Robotics vs Leading Options

Introduction

When selecting a thrust stand for professional aerospace R&D, the decision ultimately comes down to data quality, testing capabilities, and platform reliability.

The data demonstrates that Tyto Robotics' Flight Stand thrust stands are a trusted industry standard, delivering significantly higher precision and stability than other leading stands.

The Flight Stand’s solid-state design, 1,000 Hz sampling rate, and adherence to rigorous standards like ISO 21940-11 ensure your results are not only dynamic, but fundamentally more accurate and trustworthy.

Quick Comparison: Key Differences

This table highlights the core differentiating factors that make Tyto’s system superior for dynamic testing, based on real tests using a TA110 motor and 30x10 propeller.

Feature/Metric	Tyto Robotics Flight Stand	Other Leading Stands
Measurement System	Solid-State Design (Eliminates friction/gaps)	Linear Bearings (Prone to friction, dust, and misalignment errors)
Data Hysteresis	Returns to 0 g (Minimal Hysteresis Error)	Residual load of 40 g after load removal (High friction)
Usable Sampling Rate*	1,000 Hz (Essential for dynamic testing)	Typically 10−100 Hz (Static testing only)
Measurement Stability	Std Dev=3.5% (Highly stable)	Std Dev=16% (High fluctuation)
Vibration Amplification	Lowest in Class	Up to 4.5x More Vibration (In force measurement)
Coaxial Test Separation	150 mm (Realistic coaxial testing)	∼800 mm (Less realistic coaxial testing)

*The Flight Stand uses a real-time data acquisition system. This means that all data is synchronized electrically across all powertrain measurements.

The Superiority of Solid-State: Data Quality and Stability

Data Reliability: Lower Hysteresis Error

Tyto Robotics stands use a single monoblock load cell and a specialized solid-state measurement system. This design avoids the pitfalls of linear bearings, which cause friction and gaps in the force measurement system.

Hysteresis Test Results:

• In a 200 g load removal test, the Tyto stand consistently returned to a 0 g reading.
• Bearing-based stands continued to show a residual load of 40 g after removal, introducing errors that contaminate subsequent measurements.

Unmatched Stability: 3.5% vs. 16% Fluctuation

To quantify the difference in stability, a 30-second hold test was run on both systems.

• Tyto Stand (Solid-State): Showed an average thrust of 9.6 kgf with a small standard deviation of 0.30 kgf (∼3.5%).
• Bearing-Based Stand: Showed an average thrust of 9.2 kgf but with a much larger standard deviation of 1.5 kgf (∼16%).

Vibration Performance: Lower Amplitudes in Solid-State Design

Tyto Robotics stands use a solid-state design that minimizes vibration transmission through the measurement path. Bearing-based systems, by contrast, introduce additional mechanical movement that amplifies vibration and reduces the accuracy of force measurements.

• Flight Stand: In a 30-second hold test at 3180 RPM / 53 Hz, Fast Fourier transformation analysis showed stable vibration levels with low peak amplitudes in both thrust and torque measurements.
• Bearing-Based stand: The same analysis revealed up to 4.5 times higher peak amplitudes for thrust measurement and 3.7 times higher amplitudes for torque measurement, indicating significantly greater vibration in bearing-based stands.
  

This difference demonstrates that Tyto’s solid-state design provides significantly more stable and consistent readings, essential for reliable comparison and analysis.

Dynamic Testing Requires Tyto's 1,000 Hz Rate and Filtering

Capturing Fluctuations with a 1,000 Hz Sampling Rate

While many systems measure at only 10−100 Hz, Tyto Robotics provides a 1,000 Hz sampling rate. This high rate is essential to capture:

• Fluctuations in torque (e.g., torque ripple)
• Current fluctuations
• Vibration data
• Precise motor and ESC response time

Intelligent Low Pass Filtering for Accurate Results

A high sampling rate alone is not enough; the data must be processed correctly. Tyto Robotics carefully customizes its low pass filtering to maintain key dynamic data—such as vibration and torque ripple—which a poorly configured filter would otherwise remove.

Crucially, the filter is also customizable by the user, giving researchers complete control over their signal processing.

Advanced Features That Accelerate Research

Superior Testing Features and Compatibility

• Coaxial Testing: Tyto stands feature a minimum separation distance of 150 mm between coaxial systems, accurately simulating a real drone's design. Other systems often require an unrealistic 800 mm distance.

• Multi-Motor Testing: Tyto Flight Stands support distributed electric propulsion testing where you can control and test up to 8 motors simultaneously.

• Certifications: Built-in dynamic balancing adheres to the international ISO 21940-11 standard, and the load cell follows ASTM E74 and ASTM E2428 with hundreds of calibration points for verified higher accuracy.
