In the current optimization study, the response variation between two contiguous iteration cycles is caused by a small stiffness variation by tailoring the laminate layup of a wing structure
. The equivalent structure stiffness at iteration cycle N can be represented by the stiffness at previous cycle N - 1:
During WW1 the British achieved bracing wire drag reduction by developing streamlined wire cross sections, but the Germans achieved further drag reductions by using cantilever wing structure
with much fewer bracing wires.
The new organizational designed was called the Objective Wing structure
and it gave operators authority over flight-line maintenance.
The change of wing structure
deformation not only influences aerodynamic force but also changes flight pose for flapping wing.
In the framework of the contract, AIRWARE(TM) 2050 plate and forging stock will be used in the manufacturing of critical parts of the internal wing structure
contributing to reach significant weight savings and reducing the corrosion impact on aircraft parts.
"I think the biggest point I want them to take away is as they progress up through the wing structure
, how they lead and the skill sets they need must change," he said.
The two have worked together since 1999 on items such as ribs, leading edges and then wing boxes - a central part of the wing structure
Other major contracts in 2008 include Korea Aerospace Industries' $170 million contract with the U.SI Air Force for A-10 wing structure
and ones for exporting spare parts of the K-9 self-propelled howitzer to the United States, Turkey, and others, they said.
Michael Moseley signed the Global Wing Structure
Program Action Directive 08-01.
It will be utilized for cutting the composite stringers, which are part of the composite wing structure
According to Kevin Albers, the manufacturing engineer who manages the F-35 modeling and simulation efforts at Fort Worth, "All of the critical assembly sequence operations have been simulated." Completed simulations include the full assembly sequence for the wing, and the automated mating of the wing structure
with the sections of fuselage.
In the F-15, we've had structural failures where the tail has actually come off the aircraft, and we are beginning to see major cracks in the wing structure
of the aircraft.
