DARPA has launched in August its research program for Active flow control airframe demonstrator called CRANE (Control of Revolutionary Aircraft with Novel Effecters) :


I thought we needed a thread for that.

An interesting report on the program (if you discard the verbous first half dealing with Airbus) :

Aurora Flight Sciences to Develop New X-Plane Under DARPA Contract

NOVEMBER 12, 2020

Active Flow Control in early stage aircraft design will enable revolutionary capabilities

MANASSAS, Va., Nov. 12, 2020 — Aurora Flight Sciences, a Boeing Company, aims to develop an experimental plane under a new Defense Advanced Research Projects Agency (DARPA) contract. The X-plane seeks to demonstrate the advanced capabilities of Active Flow Control (AFC) as a primary design consideration.

Through DARPA’s Control of Revolutionary Aircraft with Novel Effectors (CRANE) program, Aurora is under contract for Phase 0 in partnership with Boeing and the University of Arizona. The team will develop tools and technology for incorporating AFC in the early stages of aircraft design to later demonstrate in a custom X-plane.

During Phase 0, Aurora will study AFC-enabled designs across multiple mission domains for one year to identify an X-plane demonstrator concept. Phase 1 will follow with preliminary design of an X-plane demonstrator.

“This team builds upon decades of AFC research and prototyping, including flight tests of full-scale implementations,” said Per Beith, Aurora President and CEO. “Together with DARPA, we can enable fundamentally new approaches to aircraft design and look forward to exploring game-changing configurations.”

One thing the NATO AVT-239 study on AFC brought up was that pushing (hot) bleed air
through the interior of the aircraft and out to apertures is going to have thermal implications.

You may end up trading reduced control surface deflection (and hence RCS) for worse IR signature.

@marauder2048 : I am not sure that blowing air is still used on external surface here.
Effectors should be seen here as electronic device that accelerate pre-charged (or not) air through magnetic field or locally grow the thickness of the boundary layers through heat transfer and dynamic actuation.
IMOHO nobody will blow air for cruise ctrl like it was experimented earlier. Exhaust gases on the training edge, yes, as that won't affect the IR signature otherwise than on a positive note (increased dilution).

Officials of the U.S. Defense Advanced Research Projects Agency (DARPA) in Arlington, Va., announced a $12.4 million order to Aurora late last month to move to phase-one of the Control of Revolutionary Aircraft with Novel Effectors (CRANE) project.

In this phase Aurora Flight Sciences electric aircraft experts will validate analytical predictions, carry out control loop analyses, and perform modeling verification. The company won a $7.1 million DARPA CRANE contract in June 2020 to craft configuration-agnostic designs, conduct geometric and technology trade studies, and produce process documentation.

This is not aimed at electric aircraft as the article reports, they must have gotten confused. The fluidic actuators have rather large massflow/power requirements, which is pretty taxing for electric aircraft.

Link text modified. They are focused on electrics for aviation with a high power range (follow their link). Effectors can use high voltage current. They are not all simply fluidic. Magnetodynamics needs high voltage current.

That looks like a photo of a MINION or related wind tunnel model. Just the PR hacks using a old photo for illustration purposes or is it actually being used as part of the current project? (I don't think MINION itself has been a active project recently, though I could be wrong.)

Never mind, realised where the photo actually originated. Tea infusion, stat!

Next phase launched:
Aurora Flight Sciences and Lockheed Martin Corporation are now entering Phase 1, which includes system requirements development, initial design work, software development, and initial airworthiness activities that culminate in a preliminary design review.

Alexander Walan, program manager for CRANE in DARPA’s Tactical Technology Office said, “The Phase 1 researchers have completed conceptual designs of novel flight demonstration configurations with quantifiable performance benefits enabled by active flow control.

“Multiple AFC technologies will continue to be matured through advanced analytical and testing activities for incorporation in relevant demonstrator designs.”

BAE now also selected for Phase 1 on CRANE
The U.S. Defense Advanced Research Projects Agency (DARPA) awarded the contract to BAE Systems to design a full scale demonstrator concept with Active Flow Control at its core. The aircraft’s ability to maneuver in flight without conventional flight control surfaces will enable improved performance, maintainability, and survivability.

The contract award forms part of DARPA’s Control of Revolutionary Aircraft with Novel Effectors (CRANE) project, which intends to inject Active Flow Control technology early into the aircraft design process to demonstrate significant efficiency benefits, as well as improvements to aircraft cost, weight, performance, and reliability.
