Biomimetic Flapping-Wing Micro Air Vehicles US Patents 9,428,269 and 8,700,233

A tail-less, biomimetic FWMAV that is controlled by utilizing the motion of the flapping wings themselves. By manipulating a few variables that govern the periodic motion of two wings, the time-averaged forces and moments that are applied to the FWMAV can be directly controlled. A resulting implication is that the number of vehicle degrees of freedom controlled can exceed the number of actuators that physically exist on the FWMAV, thereby shifting complexity from mechanical elements to software. Present levels of development allow roll and yaw rotations and horizontal and vertical translations to be controlled using two brushless DC motors or piezoelectric actuators that drive each wing independently.

Pseudomorphic glass for space solar cells

AFRL has developed a flexible hybrid cover glass for spacecraft solar panels comprised of small beads of either fused silica or ceria-doped borosilicate glass embedded in a matrix of conventional cover glass adhesives. These beads may also be used in a matrix of Kapton as the solar panel's substrate which may be combined with flexible solar cells to form flexible solar panels.

Real-time evaluation of change in thermal conductivity across an interface

AFRL has developed a method of using Structural Health Monitoring (SHM) techniques for determining whether changes in thermal conductivity have occurred to a particular interface between two joined structural members.

Modular deployable structure

A structure with modular construction, which contains a minimum of two panels.  One of the panels is configured to be attached to an additional structure pivotably.  The structure is deployed from and returned to the pivoting panel.

Approaches to actively protect spacecraft from damage due to collisions with ions

AFRL has developed a method where one or more conducting plates electrically-biased negatively with respect to a spacecraft's electrical potential and insulated from the spacecraft surface are located around the spacecraft surface. There, contaminant ions in a plasma surrounding the spacecraft are attracted to and accelerated through the conducting plates electric potential, caused to collide with the conductive surface, neutralized through collisions with surface atoms, and then reflected away from the spacecraft as neutral atoms or molecules.

Pulse tube refrigerator with tunable inertance tube

AFRL has developed an inertance tube for a pulse tube refrigerator which can be tuned to optimize performance. Apertures in the inertance tube fluidly communicate the inertance tube with a fluid reservoir.
