The purpose of this work is to improve the signal-to-noise ratio of acoustic measurements made in a wind tunnel with a microphone phased array. The functional beamforming method is improved to compensate for effects of acoustic propagation through turbulence, and to correct for inaccurate steering...

Each December, we ask our readers to cast their vote for the annual NASA Tech Briefs’ Readers’ Choice Product of the Year Awards. Each month, our editors choose a Product of the Month that has exceptional technical merit and practical value for our design engineering readers.

North Carolina State University researchers will use unmanned aerial vehicles (UAVs) and insect cyborgs, or biobots, to map large, unfamiliar locations.

This week's Question: A new home security technology called the Sunflower Home Awareness System deploys a drone to patrol one’s property. The combination of intelligent outdoor sensors and an aerial drone-based camera detects motion, vibration, and sound, and provides users with a view of the home’s...

This week’s Question: Ride-hailing company Uber recently released a white paper outlining its new transport service: the flying car. The company envisions a “network of small, electric aircraft that take off and land vertically.” The proposal aims to use airspace to relieve transportation...

Proto Labs, Maple Plain, MN, has launched an overmolding service. Product designers and engineers use overmolding to improve grip and durability, dampen vibration, and add two-color aesthetics to parts. Overmolded parts go through a multi-step process that results in common products like tool handles, personal care products,...

Innovators at NASA’s Armstrong Flight Research Center are developing a collection of algorithms that can accurately determine the structural state of an aircraft. This work is in response to new airframe designs that save weight — and thereby improve fuel efficiency — by removing stiffness in...

Innovators at NASA’s Armstrong Flight Research Center have developed a method of using aircraft lift airbags to support test aircraft during wing strain gage load calibration. In calibration testing, a set of known loads is applied to the wing, and the loads and strain gage responses are then recorded....

In the case of an aircraft system failure such as control surface or engine failure, an aircraft’s flight envelope may change. Notifying the pilots of these changes may improve situational awareness and, hence, increase flight safety because pilots...

Air traffic management research needs to adequately address all players, including flight crews, air traffic controllers/managers, and airline dispatchers. Interactions between the different stakeholders are crucial elements for the viability of a given concept. A simulation capable of addressing...
