Angle of attack and airspeed

Our Pitot-tube. Snout is from a combined angle of attack and airspeed Dynon Pitot-tube. Body with static ports and electronic housing is custom made by us.

Alongside measuring airspeed, it is crucial to assess the angle of attack, which is the key factor for maintaining flight. All pilots are aware that lift is determined by the angle of attack rather than airspeed. By increasing the angle of attack, a wing can stall at any airspeed, and this is a deliberate action during aerobatic maneuvers like snap rolls.

We utilize a modified Dynon Pitot-tube to measure both angle of attack and airspeed. Static ports have been incorporated to directly measure both parameters at the source via two MPXV7007DP differential pressure sensors. These sensors are sampled at a rate of 50 Hz, and the data is transmitted wirelessly to both flight data computers aboard the e131. Our Pitot tube is completely self-contained and requires only a DC power connection. It features minimal plumbing, eliminating long pressure lines and issues such as leaks or deteriorated seals.

In-flight evaluations and initial adjustments of the Pitot tube installed on Hugo’s RV-8 are scheduled for July 2026.

The Pitot-tube (not to scale - emphasized in yellow) is mounted between the upper and lower wing at the vertical strut.
