Jones investigated V-shaped tailless UAVs with a
sweepback angle of 45[degrees] on the leading edge and found that ground effects rise pitching moment and slope of lift curve and reduces induced drag, while the total drag on the UAV increases [16].
This generates the angle of
sweepback described previously.
While few discontinuous changes have occurred for technology within the airline industry, there have been some major incremental advances that have been geared toward increased efficiency--new fuselage designs such as
sweepback wings, advanced aviation systems, and information systems modifications.
(2001) Improved accuracy and reliability of
sweepback angle, pitch angle and hand velocity calculations in swimming.
While occupants get quite decent legroom in the front and rear compartments, the GEN-2's
sweepback styling is likely to inhibit some rear seat passengers.
At the same time, McDonnell Douglas made the wing thicker--the original Hornet wing had always wrestled with a lack of stiffness, which made its outer pylons of limited use--and increased its
sweepback to counter the resulting increase in drag.
Different cases are studied including gust frequency and wing
sweepback angles.
