In the cases with control with both co-flow and counter-flow configurations, the COP was clarified to become lower particularly near the trailing edge
compared with the baseline case.
The formation of vortices due to shear layer reattachment, pressure fluctuations inside the cavity during the whole feedback cycle, bending of the shear layer causing mass to leave the cavity, and the formation of high pressure zones especially at the trailing edge
wall of the cavity are shown in the figure for one Rossiter period.
C-type domain and grid are created in ICEM CFD with far-field boundaries 12.5 chords away from trailing edge
in all directions.
When the trailing edge
of the pulse enters the block, the net pressure applied to the block becomes equal to zero because the negative pressure [P.sub.M] in accordance with (5) disappears and the positive additional pressure [P.sub.A] produced by the leading edge in accordance with (6) is compensated by the negative pressure -[P.sub.A] produced by the trailing edge
But prior theoretical work carried out by Jaworski and Nigel Peake at the University of Cambridge revealed that the porous, compliant character of the owl wing's trailing edge
results in significant aerodynamic noise reductions.
As the vortex approaches the trailing edge
of the cavity, a dipole is formed releasing an acoustic wave.
They started at the starboard wingtip, continued along the trailing edge
of the flap, aft along the fuselage to the aft radome, around and up the port side, along the trailing edge
of the flap, and out the port wingtip.
Now its rear fuselage and the trailing edge
of the wings are on the ground.
Once the left wing inboard trailing edge
flap and inboard spoilers were removed, SSgt Bogard discovered a sheared bolt in a secondary support rod connected to the spoiler mount.
A report by the Air Accidents Investigation Branch published today, said the accidentwas causedbythe failure of the right wing trailing edge
retaining pin mechanism.
Note that in all the figures, the rotation of the rotor is counterclockwise so that the region immediately behind the rotor's blade is referred to as the trailing edge
region and in front of the blade is referred to as the leading edge region, as indicated in the figures.
