Using Electromagnetic Brakes to Keep Thrust Reversers IN PLACE

Applying reverse thrust redirecting engine power to oppose the direction of travel is a standard technique for decelerating aircraft after touchdown. The approach saves wear on the brakes of the landing gear wheels and reduces stopping distance. Although accidental deployment of the thrust reverser cowl could and did happen, it was assumed for decades that this would only present a hazard in the moments around takeoff and landing. With changes to engine design and aircraft aerodynamics, this assumption no longer held, as demonstrated by the catastrophic loss of Lauda Air Flight 004.

Thermostatic Solutions for Temperature Control Applications

The wax-filled thermostatic element was invented in 1936 by Sergius Vernet (1899-1968). Its principal application was in automotive thermostats used in the engine cooling system. Wax thermostatic elements transform heat energy into mechanical energy using the thermal expansion of waxes when they melt. In addition to engine cooling systems, this wax motor principle also finds applications in heating system thermostatic radiator valves, plumbing, industrial, and agriculture. Today this technology is widely used across a broad spectrum of industries including aerospace & defense, most often for temperature control of various fluid systems.

Preventing Premature Part Failures with Electropolishing

Design engineers in the aerospace industry are constantly challenged to improve fit and function of components used in commercial and military aircraft. Parts used in these aircraft must withstand high-stress, corrosive conditions with long-term use. They also must meet highly demanding cycle life specifications.

3 Key Benefits: Better Corrosion Resistance, Fatigue Life, Part Integrity

Electropolishing has become a common metal finishing process used in the aerospace industry to help improve the overall quality of metal components. These components come in many forms including high-performance fasteners, fittings, nozzles, housings, and welded assemblies. In order to maintain reliable performance, these components must be precisely manufactured and have an impeccable surface finish that is free of burrs and other contaminants.

Optical Interconnect Design Challenges in Space

More and more aerospace applications are incorporating fiber optics technology into their designs due to its many advantages over copper. The thinner fiber solutions provide higher speed over a longer distance, are more reliable, offer higher noise immunity and, in many cases, lower the cost of ownership. Additionally, for the same diameter, fiber can pack more data than copper. Fiber is faster than the category 5 and 6 copper cables, approaching the speed of light (31% lower). For copper, pushing the speed beyond 1G is a challenge, but for fiber 10G is quite common. Copper is limited by distance. Usually, signal degradation with copper will occur after about 90 meters (2.7 km maximum for custom systems), while fiber can achieve more than 1.5 km without a problem and can deliver over 80 km depending on transmission signal quality.

Ultracompact, High-Speed Field-Effect Optical Modulators

The major goals of this research project included two parts. First, an ultracompact plasmonic electro-optical (EO) modulator was to be developed and investigated for efficient intensity modulation. Second, an ultracompact and high-speed EO modulator based on a dielectric platform was to be developed for straightforward integration with existing CMOS technology. Both modulators were targeted to facilitate next-generation interconnects for integrated photonic circuits.
