Wind Tunnel Data 

This page posts results from wind tunnel tests. These plots are our technological efforts that prove the validity of our claims and the benefits our design brings. They are the strongest proof of the value of our innovation.

01
SAWTC Installation

The wing is installed in the SAWTC testing segment by a metallic frame.

02

SAWTC Surface Processing

Tape is applied to the surface of the wing to smooth the flow and place the pressure sensors.

03

SAWTC Bending Comparison

The aeroelastic bending by prediction and experiment are compared. The average percentage varience is below 4%, validating our simplified simulation results are thustworthy.

04

SAWTC Pressure Results

The direct pressure results from the sensors are fluctuating, as the plot shows. Further processing is needed to extract valuable measurement from the raw data.

05
Pressure pointal comparison

The sample point pressures are compared in order to validate the accuracy of flow simulation. All the experimented sets obtain percentage variance below 8%, and the maximum projected variance is 8.6%. Variance decreases with speed.

06

Frequency Analysis

The frequency variation plot helps determine the damping lost and the resonance frequency. It is determined with this data that this model has a natural frequency of 18.4Hz, which is consistent with evaluation.

DWT Measurement

DWT uses a graphic, economic way to directly compare the fluttering and displacements between a conventional wing and a high-speed wing.

08

Oscillation Amplitude

Fluttering amplitude under same flow velocity is decreased by over 20% on the high speed wing.

Oscillation Frequency

Oscillation frequency under same flow velocity is decreased by over 17% on the high speed wing, demonstrating the aeroelastic superiority of the wing form.
