Marine composites are materials used in the construction of off-shore structures and boat components to increase performance, decrease fuel consumption, and significantly reduce carbon dioxide emissions. They are often used as alternatives to traditional materials such as aluminum and steel. Composites such as glass fiber-reinforced plastics and CFRP are currently being widely used in the manufacture of boats and other marine vessels. Marine composites are also used in subsea applications as protection structures for subsea wellheads and valves.

High resolution calibrated near infrared (NIR) imagery of the Space Shuttle Orbiter was obtained during hypervelocity atmospheric re-entry of the STS-119, STS-125, STS-128, STS-131, STS-132, STS-133, and STS-134 missions. This data has provided information on the distribution of surface temperature and the state of the airflow over the windward surface of the Orbiter during descent. The thermal imagery complemented data collected with onboard surface thermocouple instrumentation. The spatially resolved global thermal measurements made during the Orbiter s hypersonic re-entry will provide critical flight data for reducing the uncertainty associated with present day ground-to-flight extrapolation techniques and current state-of-the-art empirical boundary-layer transition or turbulent heating prediction methods. Laminar and turbulent flight data is critical for the validation of physics-based, semi-empirical boundary-layer transition prediction methods as well as stimulating the validation of laminar numerical chemistry models and the development of turbulence models supporting NASA s next-generation spacecraft. In this paper we provide details of the NIR imaging system used on both air and land-based imaging assets. The paper will discuss calibrations performed on the NIR imaging systems that permitted conversion of captured radiant intensity (counts) to temperature values. Image processing techniques are presented to analyze the NIR data for vignetting distortion, best resolution, and image sharpness.

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.

A military rotorcraft is a special type of rotorcraft that is produced to fulfill the demands and requirements of the defense forces. Military rotorcraft are basically used for transport purposes;however, they are also used in medical evacuation, rescue, and search operations. Some rotorcraft are armed with weapons and used to attack ground targets and for other combat purposes. Currently, there is a high demand for military rotorcraft due to unique features such as vertical take-off and landing, ability to hover, ability to fly forward, backward, and lateral. These rotorcraft are capable of landing and taking off in difficult terrains (deserts and high mountains where climatic conditions are extreme) and where the harsh terrain makes it difficult to build runways for military aircraft.

A submarine is a vessel that operates underwater. It is generally used by the Navy and is considered to be one of the most powerful defensive weapons used during wars.The Global Submarine market is expected to witness high growth during the forecast period. In 2013, the Americas dominated the market, followed by the EMEA and APAC region. The current demand for seating systems is mainly from developed countries, but this is expected to shift slowly toward the developing countries over the next few years. The market is predicted to grow at a CAGR of 3.27 percent during the forecast period.

The selling price of electrical power varies with time. The economic viability of space solar power is maximum if the power can be sold at peak power rates, instead of baseline rate. Price and demand of electricity was examined from spot-market data from four example markets: New England, New York City, suburban New York, and California. The data was averaged to show the average price and demand for power as a function of time of day and time of year. Demand varies roughly by a factor of two between the early-morning minimum demand, and the afternoon maximum; both the amount of peak power, and the location of the peak, depends significantly on the location and the weather. The demand curves were compared to the availability curves for solar energy and for tracking and non-tracking satellite solar power systems in order to compare the market value of terrestrial and solar electrical power. In part 2, new designs for a space solar power (SSP) system were analyzed to provide electrical power to Earth for economically competitive rates. The approach was to look at innovative power architectures to more practical approaches to space solar power. A significant barrier is the initial investment required before the first power is returned. Three new concepts for solar power satellites were invented and analyzed: a solar power satellite in the Earth-Sun L2 point, a geosynchronous no-moving parts solar power satellite, and a nontracking geosynchronous solar power satellite with integral phased array. The integral-array satellite had several advantages, including an initial investment cost approximately eight times lower than the conventional design.

The electric power system is a crucial element of any mission for the human exploration of the Martian surface. The bulk of the power generated will be delivered to crew lifesupport systems, extravehicular activity suits, robotic vehicles, and predeployed in situ resource utilization (ISRU) equipment. In one mission scenario, before the crew departs for Mars, the ISRU plant operates for 435 days producing liquefied methane and oxygen for ascent-stage propellants and water for crew life support.
