China has emerged as the world's second largest country for the Aviation market. With a GDP growth rate of more than 7 percent, the country exhibits excellent opportunities, especially in the Aerospace market. Owing to this tremendous growth, there has been an increase in demand for commercial aircrafts by airline companies. The Chinese government is also increasingly encouraging Chinese companies to manufacture indigenous commercial aircrafts to meet the rising demand and also to boost the economic growth of the country. An increase in the Manufacturing sector would enhance the employment rates and GDP of the country.

An electric current sensor based on Faraday rotation effect in optical fiber was developedfor measuring aircraft lightning current. Compared to traditional sensors, the design hasmany advantages including the ability to measure total current and to conform to structuregeometries. The sensor is also small, light weight, non-conducting, safe from interference,and free of hysteresis and saturation. Potential applications include characterization oflightning current waveforms, parameters and paths, and providing environmental data foraircraft certifications. In an optical fiber as the sensing medium, light polarization rotateswhen exposed to a magnetic field in the direction of light propagation. By forming closedfiber loops around a conductor and applying Ampere’s law, measuring the total lightrotation yields the enclosed current. A reflective polarimetric scheme is used, wherepolarization change is measured after the polarized light travels round-trip through the sensing fiber. The sensor system was evaluated measuring rocket-triggered lightning overthe 2011 summer. Early results compared very well against a reference current shuntresistor, demonstrating the sensor’s accuracy and feasibility in a lightning environment.While later comparisons show gradually increasing amplitude deviations for anundetermined cause, the overall waveforms still compared very well.

Argon is a flight-ready sensor suite with two visual cameras, a flash LIDAR, an on- board flight computer, and associated electronics. Argon was designed to provide sensing capabilities for relative navigation during proximity, rendezvous, and docking operations between spacecraft. A rigorous ground test campaign assessed the performance capability of the Argon navigation suite to measure the relative pose of high-fidelity satellite mock-ups during a variety of simulated rendezvous and proximity maneuvers facilitated by robot manipulators in a variety of lighting conditions representative of the orbital environment. A brief description of the Argon suite and test setup are given as well as an analysis of the performance of the system in simulated proximity and rendezvous operations.

The long-term goals of this project are to enable observations of pH in the ocean at depths to 2000 m using sensors deployed on autonomous platforms, particularly profiling floats of the type used in the Argo array. These systems will enable robust, basin-scale observations of changing pH driven by natural and anthropogenic processes. Develop a robust and stable pH sensor for deep-sea applications that is based on the Honeywell Durafet Ion Sensitive Field Effect Transistor (ISFET). The sensor should operate to depths of at least 2000 m. It should have a precision of 0.001 pH and a stability of 0.005 pH over periods up to 5 years throughout the oceanic temperature and salinity range. Capabilities will be demonstrated with deployments on four Webb Research Apex profiling floats.

Composite materials are increasingly used in modern aircraft for reducing weight, improving fuel efficiency, and enhancing the overall design, performance, and manufacturability of airborne vehicles. Materials such as fiberglass reinforced composites (FRC) and carbon-fiber-reinforced polymers (CFRP) are being used to great advantage in airframes, wings, engine nacelles, turbine blades, fairings, fuselage and empennage structures, control surfaces and coverings. However, the potential damage from the direct and indirect effects of lightning strikes is of increased concern to aircraft designers and operators. When a lightning strike occurs, the points of attachment and detachment on the aircraft surface must be found by visual inspection, and then assessed for damage by maintenance personnel to ensure continued safe flight operations. In this paper, a new method and system for aircraft in-situ damage detection and diagnosis are presented. The method and system are based on open circuit (SansEC) sensor technology developed at NASA Langley Research Center. SansEC (Sans Electric Connection) sensor technology is a new technical framework for designing, powering, and interrogating sensors to detect damage in composite materials. Damage in composite material is generally associated with a localized change in material permittivity and/or conductivity. These changes are sensed using SansEC. Unique electrical signatures are used for damage detection and diagnosis. NASA LaRC has both experimentally and theoretically demonstrated that SansEC sensors can be effectively used for in-situ composite damage detection.

Japan is a potential market for the manufacture of commercial aircraft parts and MRO services. Currently, there is no company in Japan that completely manufactures commercial aircraft. Thus, the country relies on the import of commercial aircraft from other regions such as North America and Europe. However, there are some vendors in Japan that manufacture commercial aircraft parts for Airbus SAS, The Boeing Co., Bombardier Inc., and Embraer SA. Mitsubishi Heavy Industries Ltd. is one such player in the country; Mitsubishi Heavy Industries is in the process of manufacturing MRJ, which is expected to be launched in the market in the coming few years.
