NASA Johnson Space Center developed reprogrammable and interchangeable electronic controllers that can attach to a system or subsystem wirelessly or through plug-and-play capability. Originally designed to work with rocket engines, this technology can control...
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 has an incredibly high energy density — double that of gasoline and an order of magnitude greater than...
Over the past 60 years, NASA scientists and engineers have developed many advanced technologies and processes. But NASA has also partnered with industry, using commercially available products to complete its missions. Here, some of those companies join NASA in celebrating these collaborative successes.
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...
Supercapacitors are rechargeable energy storage devices that deliver more power for their size than similar-sized batteries. They also recharge quickly, and they last for hundreds to thousands of recharging cycles. Today, they are used in hybrid cars’ regenerative braking systems and for other...
NASA's Glenn Research Center has developed a novel Double-acting Extremely Light Thermo-Acoustic (DELTA) converter that operates at high frequencies (>400 Hz) with greatly...
Innovators at NASA’s Glenn Research Center have developed a simple, lightweight, inline, two-speed drive that can be used either as an overall transmission, or as a supplemental add-on input...
NASA Langley Research Center has developed Greased Lightning, the first unmanned aerial vehicle (UAV) that combines vertical take-off and landing (VTOL) capability with...
Current engines and combustors run at high temperature, which leads to problems of engine knocking, soot and NOx emissions, and difficulty in combustion control. On the other hand, low-temperature combustion and fuel...
Large-scale liquid rocket engines with regeneratively cooled nozzles will enable reliable and reduced-cost access to space. The coolant that circulates through the internal...
Many aircraft need to operate efficiently at more than one flight regime; for example, certain airframes are expected to perform in relatively high-speed cruise modes, as well as slower loitering scenarios. Unfortunately, an engine operates most efficiently when the exit velocity closely matches the speed of the...
Innovators at NASA’s Glenn Research Center have made several breakthroughs in treating hexagonal boron nitride (hBN) nanomaterials, improving their properties to supplant carbon nanotubes in many applications. These inventors have greatly enhanced the processes of intercalation and...
Batteries and combustion engines each have distinctive benefits and limitations. Batteries have simple construction and operate silently; however, their energy density (i.e., the energy per unit volume) is poor, and...
The robotic gripper was developed at NASA Goddard Space Flight Center as part of a robotic satellite servicing mission. The gripping device can be used to autonomously or remotely grasp and...
Thruster-based control typically requires a substantial engineering effort in order to mitigate an important issue: the control system tends to use many thruster pulses to accomplish what a single thruster pulse could do instead. This fundamental...
The advent of cryocooler technology ushers in an era where a cryogenic environment is created and maintained locally. It is no longer necessary to transport cryogen from a factory where it is produced to the...
