A rather interesting proposal by the Air Force has been issued. It calls for Aerospace Systems Efficiency Improvements for Legacy Aircraft.
Specifically tanker/transport aircraft.
It seems pretty straight forward when you read it. It talks about blending certain join areas, tightening panels to close gaps between them, removing
vortex generators that are no longer necessary, and some alterations to shaping on certain areas of wing. The entire process requires changes that
can be made to the aircraft without a redesign taking place, and basically a bolt on change. It also allows for changes to the engines to make them
Then there is a VERY interesting curveball thrown in. Included in the proposal is also the ability to make alterations to stall control/high lift
devices, by making them deployable/deformable, methods for gust load alleviation, and various flow control devices. Even more interesting is that it
also includes the addition of passive or active laminar flow control devices.
Then there's this tidbit thrown in:
One possibility is modernization of classic panel methods, to include nonlinear panels, tolerance of non-watertight geometries, parametric
geometry definition for rapid analysis of alternatives, and lumped-parameter models of flow control devices. The latter might include flow-through
panels to simulate fluidic flow control, or time-dependent body forces to simulate plasma flow control.
There has been talk from both the US and Russia about using plasma on aircraft for years, but nothing concrete has come out. One of the uses was for
stealth, as the plasma would absorb all signals coming in and out. There is a very interesting thread on it
Is this the first concrete evidence that plasma is in use? Does this mean we might see it coming out of the dark soon? From what I've heard about
it, if it was in use, the advantages would be immense, as it would allow for better range on the aircraft, as it would lead to less drag on the
This will be very interesting to watch in the next couple of years to see if this comes out into the white world.
