Appointed to this position in October 2010, Bowers is part of the NASA Dryden strategic planning team that is developing research projects for future aerospace concepts. As part of that team, Bowers is responsible for defining NASA Dryden's strategic direction for the Center, including advanced aeronautical designs, research and space technologies.

Prior to his present position, Bowers served as Director of Dryden’s

A Naturally Micro Flyer

Filed under the keywords

This prototype flapping wing micro air vehicle is the first of its kind, because of its ability to flap each wing independently. This vehicle, designed and built by the artists, was used to test flight control algorithms for hovering flight. Fabricated from advanced composite materials, it has a wing span of 8 centimeters, weighs less than a gram and is powered by piezo-electric crystal actuators.

Alien On the Tip of a Plasma Torch Cathode Tip?

Filed under the keywords

Various structures (and perhaps even an alien) can be seen in the ~600 micrometer diameter crater formed on the tip of a plasma torch igniter cathode. The structures were formed as the melted tungsten at the tip solidified while cooling from temperatures in excess of 6600°F.

Archimedes Defeats Newton

This is a horizontally issuing buoyant ethylene flame. Flow thru a 3/8 in tube at 9.82 SLPM. Imaged with a 40 microseconds exposure time using a Phantom v12.1 camera.

Break Out The Guns!

Filed under the keywords

This image depicts operation of a 9-stick Gatling-Gun micro PPT thruster firing. Sticks fire seqentially from 1 to 9, but long expose setting captures all 9 firing in brilliant detail.

Breakdown

Filed under the keywords

An arc forms as the dielectric fails during an atmospheric pressure, wire-to-plate dielectric barrier discharge (DBD) in air. DBDs form the basis of plasma actuators, which are an emerging technology for controlling low-speed flows.

Brian Binnie

Filed under the keywords

Test pilot for Burt Rutan’s award winning SpaceShipOne, Brian flew the first and the last powered flights of the vehicle. In the process he opened up the vehicle’s envelope to supersonic flight, beat the long standing altitude record of the X-15 and clenched the $10M Ansari X-Prize.

Computational Study of a DISI Rotary Engine

Filed under the keywords

Due to the inherent low fuel efficiency of rotary engines and increasing gas prices, application of the rotary engine in conventional automobiles is decreasing. This project seeks to introduce DISI technology to the rotary engine, thus increasing the fuel efficiency and allowing it to be another efficient power source option for aero and automotive applications.

Crystal Angel Hair

Filed under the keywords

An image taken with a Polarizing Optical Microscope of a liquid crystalline polymer in the super cooled RT state. The polymer was melted into a nematic phase first, supercooled below the nematic/crystalline transition. The polymer crystallizes with the underlying texture of the nematic phase still present, leading to the hair like texture.
