Technical observations/ questions on the 10/23 Raptor video:
1. Observation - The nylon tufts appear really stiff compared to yarn ones.
Question - How much flexibility is needed to be able to ascertain the flow behavior?
2. Observation - As mentioned in the video, there appears to be turbulence near the hull on the canard.
Question - Is turbulence near the canard/hull joint normal?
3. Observation - As mentioned in the video, there is turbulence at the landing gear hull opening. There also appears to be a suction into the slot at the tuft near the N on the leading edge of the slot (though it could just be hidden in the shadow and flowing straight).
Question - How much turbulence is expected on other retractables in similar positions?
4. Observation - The wheel well covers are held by a single layer of tape.
Question - Are there any examples of where a smooth flat surface similar to this was taped and released due to failure of the tape?
5. Question - Were there other observations of note in this video?
