Silicon carbide matrix composite with increased fracture toughness and thermal shock resistance
Ceramic matrix composites are expected to replace the conventional alloys/metal components in the aircraft engines. While maintaining its thermal shock resistance and fracture toughness, this novel SiC fiber-reinforced SiC material is free from fiber/matrix interface thus does not require a costly process to control interface thickness to prevent its oxidation.
A Novel Decontamination Process for Powders for Transparent Ceramics
The invention describes a pretreatment process to remove unwanted impurities in ceramic powders by treating powders in ultra-high vacuum with or without concurrent heating for extended period of time. The process does not modify the physical characteristics of the powders resulting in better product quality because of reduced batch-to-batch variations.
Global/Local Monitoring of Energy Consumption
Increasing electric energy production leads to consequences unknown right now. Satellite observations of triggered by terragenic impacts emissions present possibility for monitoring man-made impacts and forecast possible critical levels. Further methodology development may provide a tool allowing monitoring energy production and consumption on both planetary and local scales.
Automatic Dependent Surveillance Broadcast (ADS-B)
NASA Armstrongâ€™s automatic dependent surveillance broadcast (ADS-B) system provides enhanced communications, command-and-control operations, and efficient sense-and-avoid capabilities for unmanned aerial systems (UAS). This innovation solves many of the technical problems related to the safety and operation of UAS in the National Airspace System (NAS) shared with traditional aircraft.
Improved Ground Collision Avoidance
NASA Armstrong has developed an improved ground collision avoidance technology for aircraft. Using algorithms developed for fighter aircraft, this mobile/handheld platform that can be used on general aircraft. The system offers high fidelity terrain mapping, enhanced vehicle performance modeling, multidirectional avoidance techniques, and user-friendly warning systems.
Novel Peak-Seeking Algorithm to Optimize Performance of Dynamic Systems
This peak-seeking control algorithm automatically optimizes a dynamic system in real time to meet a specified performance objective. Originally developed for aviation applications, this algorithm can be applied to a broad class of engineering problems in a wide range of industries.
Software for Real-Time, High-Resolution Terrain Information in Computing-Constrained Environments
Data adaptive algorithms are the critically enabling technology for automatic collision avoidance system efforts at NASAâ€™s Armstrong Flight Research Center. These Armstrong-developed algorithms provide an extensive and highly efficient encoding process for global-scale digital terrain maps (DTMs) along with a real-time decoding process to locally render map data.
Non-Specular Reflective Surface Treatment
A surface treatment to break up the reflections of radio waves to eliminate dropouts and hot spots. For radio waves, this surface, compared to a flat surface, is reflective in a way similar to how a piece of white paper is reflective compared to a mirror for visible light.
Variable geometry fuel injector for internal combustion engine
Compact, High Temperature Nanolayer Film Capacitors
Multilayered films of polyvinylidene fluoride and polycarbonate were fabricated to show a 2 fold improvement in energy density, 50% reduction in existing capacitor size, and up to 160 Â°C performance with improved breakdown strength. Capacitor fabrication and testing validated the results. Scale-up production of films was also demonstrated.
Artificial Olfactive System
Olfactive sensor that identifies and locates the source of an odor at distance composed by the principal features of a biological nostril and the olfactive cycle. Each nostril has the ability of odor absorption to desaturate the sensors and avoid a path trail, reaching the source directly.
Propulsion system based on two electric motors and control method
A modular propulsion system that combines the input of two electric motors with the objective of provide operation on a higher efficiency zone in the efficiency map of the motors. The propulsion system is based on planetary gear trains and can provide 4 operation modes and fault tolerant operation.
Air Data Sensor Probe
A novel sensor design allows capture of angular fluid flow with greater accuracy than the conventional Pitot-type probe currently in use in commercial and military aircraft. This invention is most likely to be used in the aerospace industry as an onboard sensor for flight data and avionics systems.
