Air Force Working on Fuel-Saving, 3D-Printed ‘Microvanes’ for C-17 | Air & Space Forces Magazine

The Air Force is considering retrofits of small microvanes to its C-17 cargo planes in an effort to save on fuel.

Aerodynamic technologies for mobility aircraft promise high return on investment

As part of its effort to increase readiness and capability, the Air Force is working to introduce aerodynamic technologies on mobility aircraft to improve airflow, reduce maintenance issues, increase
www.af.mil
After several years of research and testing, microvanes for the C-17 are in the process of airworthiness certification at the AFRL and the Air Force Life Cycle Management Center. Microvanes are small 3D-printed structures that attach to the aft-end of the fuselage. The fin-like shape helps redirect airflow in this higher drag area, streamlining the aerodynamics and reducing overall fuel demand by approximately 1%.
When installed across the C-17 fleet, including Air National Guard and Air Force Reserve aircraft, the Air Force estimates the microvanes will pay for themselves in fuel savings in seven months, and save over $10 million per year.

Interesting cost valuation of C-17 flights (but does not come as a surprise) :

military deportation flight to Guatemala on Monday likely cost at least $4,675 per migrant, according to data provided by U.S. and Guatemalan officials.
That is more than five times the $853 cost of a one-way first class ticket on American Airlines from El Paso, Texas, the departure point for the flight, according to a review of publicly available airfares.

Does this mean no new DoD transports & tankers? If not, then big DoD problem.

That article reaches new levels of utter crap. Starting with not putting a date on it, but "CEO Dave Calhoun,... will leave later this year." dates it to last year.

Its main claim is that Boeing is shutting down production of wide-bodies - that's the 767, 777 and 787. Boeing Commercial Airplanes actually announced: "Commercial Airplanes also plans to conclude production of the 767 freighter." So only the commercial 767F, nothing to do with KC-46 (except they'll lose any synergies that might have been keeping their losses on KC-46 down).

It then illustrates the claim with pictures of the C-17, which despite being wide, isn't a widebody. Worse, C-17 production shut down a decade ago. (Sales since have been of the 15 whitetails that were built speculatively without a buyer)

The author clearly had no idea what a widebody is.

Pilots still gotta have their flight hours, so if the plane needs to be airborne anyways, might as well get some use out of it!

Surely using ships would be cheaper?

Air Force Conducts More Deportation Flights; Armed Crew on C-17s

A number of years ago, think it was under Obama, they sent Haitian illegals back on airliners. As they headed back to Haiti, they figured out they were not going on vacation and utterly destroyed the interior of the airliner so I can see why the shackles and C-17 as the mode of transportation. I do like the ship idea though....

Enjoy the Day! Mark
