High temperature for aerospace and defence electronics include standard products and custom solutions for power management, signal under extreme temperatures and harsh conditions conditioning and energy conversion. High reliability products have to be ensured from - 55?C to + 225?C and sometimes use outside that range, from cryogenic low to upper ends.
Aerospace requires saving energy, weight and cost in compact electronic systems. Often mission-critical, high temperature standard electronic components include DC-DC converters solutions regulatory voltage, voltage references, alarms & clock, analog - generator electric motor drivers to-Converters Amplifiers, Power MOSFET and controllers, digital integrated circuits (ASIC) or hybrid assemblies multi-chip.
From design through simulation, the wafer Assembly, thousands of hours of testing, high-temperature electronic components that are cutting technology life characterization process. All flight control actuators aircraft, such as pumps fuel, landing gear or actuators, brake components use. Political, environmental and economic trends for air transport lead us towards All Electric Aircraft (SAA). Electrifying aircraft provides opportunities to reduce emissions of carbon dioxide and weight and reduce maintenance costs. Electric aircraft design all aims to eliminate as many sources of hydropower and complicated circuits as possible. The replacement of conventional hydraulic systems includes replacement of all hydrostatic actuators with EMAs electromechanical actuators.
Electronics design.
At high temperatures, you start to enter an area where regular solder melts and isolation disintegrates. Commercial TTL and CMOS devices have been tested successfully with temperatures than its specified limit.
High temperature operation is not only a problem of semiconductors. Internal heat dissipation is caused by conduction losses. To minimize, low on resistance devices operated low currents possible leakage and minimum should be used. Due to leakage increases with temperature, which in turn increases the fugue, the danger of thermal leakage is always present.
Aviation-database.com is a great help to anyone who operate within the industry. "Purchase of" or "sell to" aerospace companies, placeable email contacts directly to your Outlook Express address book, you can compile a list of addresses in a print basket, you can use links to bounce directly in other aerospace company Web sites. High-temperature components and inertial sensors are inertial AeroSystems UK offer an advertiser in aviación-base data.
