Abstract

Description

VIREO / Day14 / Flight28. TEST: Closed-loop control law validation. RESULT: Good flight for control law validation. However, the aircraft crash-landed and incurred some damages. EVENTS: 1. This was a right elevon-hold flight. The throttle tracked total energy. The left elevon tracked the roll angle. 2. We performed a 150 m radius left circle for the entirety of the flight. 3. We performed an aborted autoland in bravo mode. The aircraft dropped below the virtual runway altitude of 100 ft. In addition, a manual go-around could not be attempted in time. As a result, the aircraft came in hard and crash landed. See damage assessment above. 4. The plan is to fix the Vireo and resume flight testing.
