NASA Armstrong flight-tests some of the nation’s most unique aircraft and aeronautical systems.

A lake is usually a picture of serenity, perhaps the last place you’d expect to find a flying-fish robot launching itself 85 feet in the air.

Microrobots that can deliver drugs to specific spots inside the body while being monitored and controlled from outside the body have been developed that also can treat tumors in the...

We interviewed an industry expert about the role of inductive position sensors in the IIoT.

Engineers today are feeling the pressure to get more done in less time, be experts in multiple disciplines, and use their resources more efficiently to maximize profits. This environment is shifting the way...

The Moon is a treasure chest of science. The lunar samples returned during the Apollo program dramatically changed our view of the solar system, yet they just scratch the...

Employing fluid power to achieve mechanical motion can be implemented via hydraulics using uncompressible liquids or via pneumatics using compressible gasses; typically, air. The latter provides several...

Directly converting electrical power to heat is easy; however, converting heat into electrical power is not as easy. To address this issue, a tiny silicon-based device was developed that can...

Three new unmanned helicopters were unveiled at AUVSI’s XPONENTIAL show in Chicago.

As always, the Air Force Research Laboratory had a huge presence at AUVSI’s XPONENTIAL show in Chicago.

You think riding your Harley Davidson is exciting? Try the ElectraFly.

Mechanical systems such as engines and motors rely on two principal types of motions of stiff components: linear motion, which involves an object moving from one point to another in a straight...

Making electric cars lighter also involves reducing the weight of the motor. One way to do that is by constructing it from fiber-reinforced polymer materials. A new cooling concept...

Recent technical advances have enabled flywheel energy storage systems (FESS) to become more compact and able to support higher-power applications. Due to their proven...

Spinoff is NASA’s annual publication featuring successfully commercialized NASA technology. This commercialization has contributed to the development of products and services in...

An optical setup developed by researchers at Sandia's Combustion Research Facility and the Technical University of Denmark can now quantify the formation of soot — particulate matter consisting...

Government infrastructure facilities such as water treatment facilities, power plants, laboratories, and the like may be targets for terrorist attacks. Similarly, oil pipelines, power grids,...

There are few industries where the demands for material testing and quality assurance are more challenging than in the aerospace industry. Ensuring the safety of all...

Typical direct-injection engines, such as diesel engines, can produce soot due to fuel-rich combustion conditions. Filters and catalytic converters are currently used to reduce soot and harmful...

Researchers have developed a new propulsion concept for swimming robots that exploits temperature fluctuations in the water for propulsion without the need for an engine, propellant, or power supply.

Since the first airplane took flight, virtually every aircraft has flown with the help of moving parts such as propellers, turbine blades, or fans that produce a persistent, whining buzz. MIT has built the...

ALUMINUM-POWERED ELECTRICITY GENERATION

Aluminum has an incredibly high energy density — double that of gasoline and an order of magnitude greater than...

The objective of this effort was to design, fabricate, integrate, and fly a nuclear thermal rocket without having to build massive ground test facilities. Furthermore, this nuclear rocket...
