One propeller blade was bent aft, and neither of them exhibited leading edge gouging or chordwise
Pressure taps were installed spanwise and chordwise
along the wing at several sections.
In contrast to the previous study that consider the chordwise
and spanwise flexibility of the wing, the flexibility of the wing in this paper is mimicked as the passive pitching motion by connecting a rigid wing to a torsional spring; therefore, the flexibility is just lumped at the root of the wing, and the simplified wing is in reasonable agreement with the natural insect wing .
In particular, the thickness of the blade changes continuously in both spanwise and chordwise
Here only the first spanwise mode is retained according to Dowell's work in 1966 , because compared to the bending in chordwise
, the bending in spanwise is much smaller.
The first vertical bending and first chordwise
bending are influenced mostly by the geometrical nonlinearity, and the frequencies of these two modes are dropped by 25.6% and 27.4%, respectively.
The wings rotate to the vertical (chordwise
) and pivot toward the back, where a fixture secures them for towing.
"The tip of the blade exhibited a slight forward bend, and chordwise
scratches were noted on the cambered side of the blade," the report stated.
It was resulted a surface finish with a noticeable distributed roughness as well as low chordwise
ridges due to resin overcure in at the build layer interfaces.
The computed Cp will be compared to 21 spanwise sections [0:5:100] with 5% increment and 107 chordwise
Sometimes I block the star's light with a simple occulting bar fashioned from a matchstick glued chordwise
across a paper tube, inked black, and fitted into the eyepiece barrel.
It flows along chordwise
convection cooling channels between the spar and the shell and returns to the remaining spar cavities (the discharge cavities).
