The battery requirements of aircraft manufacturers and airlines in the 1970s and 1980s were for longer life and everincreasing electrical performance in areas such as powertoweight ratio and energy density but, towards the end of the 1980s, a major additional requirement became apparent a...
A recent ERA conference covered a wide range of advanced topics. The first session, Operational Challenges, featured civil and military contributions from airlines, the RAF and a research institute. The latter considered the fact that new airliners, runways, passenger terminals and...
The enormous cost of corrosion in aircraft is of major concern to manufacturers, airlines and the armed forces. Affecting structures, components and engines, it manifests itself in a variety of different ways.
Electropolishing or, to give it its more precise title, electrochemical polishing, has now become an accepted finishing aid in the aerospace industry. Few processes offer the highly advantageous technical characteristics achieved by a treatment once derogatively referred to as reverse plating.
Electroplated coatings of zinc have been successful in protecting steel components against corrosion for many years. However, with the introduction of more exacting standards, the performance of the traditional zinc finish has not been considered up to the mark. Alternative protective systems...
Copperbased alloys are widely used in aircraft engineering where critical components require materials of construction with high strength, good ductility and resistance to corrosion. These components are often safetycritical and longterm reliable operation is a paramount consideration. A number...
The aircraft and aerospace industry still offers many unique technical challenges, resulting from the continuing drive to achieve greater allround performance and economy.
The new ACQuLab dataacquisttion system from Gould Instrument Systems is a highperformance instrument which is designed to make the acquisition and analysis of lest data easier, faster and more efficient.
A new, nonexplosive actuator NEA developed by G&H Technology holds tensile loads of up to 12,500lb and quickly releases them when electronically activated. The Model 1203 actuator is stated to be safe, fastacting and highly reliable, and release occurs with minimum shock. The actuator is ideal...
A Boeing 747 flying testbed, powered by the first RollsRoyce Trent 800 flight engine, has recently completed a series of successful trials in preparation for the start of the Trentpowered Boeing 777 flight test programme, in May 1995.
