Large axial load forces and extreme temperature ranges are typical for scientific balloon missions. Therefore, a durable, flexible, and thermally stable sensor material is needed. In this innovation, sensors have been designed to be integrated onto...

An integrated communications and control system for unmanned aircraft systems (UAS) utilizes automatic dependent surveillance broadcast (ADS-B) technology. The prime objective of this system is to address safety concerns related to UAS sharing airspace with...

LDSD (Low Density Supersonic Decelerator) is a Mars EDL (entry, descent, and landing) Technology Development Project that launches three test vehicles out of the Pacific Missile Range Facility in Kauai. On the test vehicle, most mission science data can be recorded safely on land;...

Half-Cycle Crack Growth software offers a reliable method for calculating theoretical fatigue crack growths that could lead to catastrophic structural component failures. The program builds upon and integrates Armstrong’s proven half-cycle and closed-form aging theories, and considers every half-cycle of loading spectra...

A document discusses the Ultra Compact Cloud Physics Lidar, a biaxial lidar with a narrow receiver field of view. It requires tight optical alignment between the transmitter and receiver paths while flying on various aircraft over various temperatures and in the presence of vibration. To achieve...

Peak-seeking algorithms optimize physical processes in real time and are widely used throughout a variety of industries. However, measuring associated parameters in changing conditions, and responding to them appropriately, is difficult because the measurements are typically distorted by noise. This technology addresses...

This invention relates to the safe, reliable, and repeatable testing under external load of the Extraction Force Transfer Coupling (EFTC) currently used in the extraction of airdrop platforms from both the C-17 and C-130 cargo transport aircraft. The invention enables functional testing of the EFTC...

One of the more critical constraints to the continued growth of air traffic is the related concern regarding aircraft noise. This concern has resulted in increasingly stringent noise restrictions for airports, both nationally and internationally. One of the major stretch goals for NASA is to...

Traffic flow management (TFM) of the National Airspace System (NAS) endeavors to deliver flights from their origins to their destinations while minimizing delays and respecting all capacities. There are several models for solving this problem. Some models aggregate...

Low-cost, flexible spaceborne radar architectures are needed to provide critical data for Earth and science applications. An instrument concept was developed for an advanced spaceborne radar system that can measure terrestrial biomass (woody mass per unit area), ecosystem structure (height and density), and...

A standoff sample collection system would be capable of quickly obtaining a sample from environments as varied as comets, asteroids, and permanently shadowed craters on the Moon from vehicles ranging from traditional planetary spacecraft to platforms such as hovering rotorcraft or balloons at...

Aircraft noise is a significant problem with both economic and public health implications, especially for communities near airports. As a result, increasingly stringent constraints are being placed on aircraft carriers worldwide to reduce this noise. The current disclosure focuses on airframe noise generated at or...

In this innovation, a method makes use of a new technique for describing analog information based on the roots of polynomial functions of infinite degree. Monotonic analog signals are transformed into characters that are fused into a two-dimensional composite visualization of the generating signal...

Saturn’s moon Titan is of high interest for in situ study due to its many intriguing features. This moon has a dense atmosphere; rough, icy terrain; and low surface winds that make it the ideal place to send a controlled aerial robotic platform, such as...

Mars Science Laboratory (MSL) surface operations require precise and accurate knowledge of rover position. A key means of establishing/verifying position is to match ortho-rectified mosaics from the MSL onboard cameras to orbital data. Manual localization by matching mosaics to HiRISE...
