Goodrich DuraTherm Defeats Ice

DuraTherm’s heating mat protects helicopter engine inlets from icing up. The technology was recently proven by a test at NASA Glenn’s icing research tunnel, where the DuraTherm system was installed in a Boeing AH-64 Apache engine inlet sectional mockup. DuraTherm heater mat technology works by embedding an electronic mesh into an advanced durable composite material. This material is then employed to form engine nose gearbox fairings. Besides adding anti-icing capability to the fairing, the mesh helps make it resistant to fatigue and foreign object damage. The benefits provided are increased overall system reliability, enhanced operational capability and improved flight crew safety. The U.S. Army Apache fleet is to be equipped with DuraTherm as part of its Block III upgrade program. For further information:

Quick Multipin Interconnect Connector


Radiall has released its new Quick Multipin Interconnect (QMI) connector. Developed in concert with Boeing, the QMI connector combines highly complex molded parts with high performance metallization of composite parts. According to Radiall, the "revolutionary" QMI connector makes it easier to integrate and install multipin connectors.

Among its features, the QMI connector is tool-less and quick mounting; uses a slide locking-system; equipped with an automatic rail locking mechanism that provides connector grounding; has integrated ground blocks; and uses an integrated backshell design. For further information:

Cobham Synthetic Vision System Approved

The FAA has approved Cobham Avionics’ synthetic vision glass cockpit for use in the Bell 412. The Cobham synthetic vision glass cockpit — a.k.a. the Electronic Flight Instrument System (EFIS) — provides pilots with a clear view of their surroundings, despite darkness and poor visibility conditions. The EFIS uses synthetic vision 3D technology to translate the terrain ahead of and around the helicopter into an intuitive, real-time visual picture. This helps the pilot "see" his aircraft’s position in relation to its surroundings; no matter how dark it is, and how limited the field of vision is due to clouds and smoke. The Cobham EFIS reduces instrument scanning and pilot fatigue by integrating the readouts of all primary flight instruments into one efficient tool. For further information:

SAC 7-35 Airdata Computer

Sandia Aerospace’s new SAC 7-35 Airdata Computer has received FAA-TSO approval. This is a cutting-edge computer specifically designed to work with today’s integrated avionics.

In terms of capabilities, the SAC 7-35 is really four systems in one. First, the SAC 7-35 is TSO’d as an altitude encoder; providing both Gilliam Grey Code for legacy transponders and RS 232 pressure altitude outputs for modern units. Second, by adding a fuel flow transducer(s) to your aircraft, the SAC 7-35 can track and provide fuel flow data to navigation systems that offer fuel flow displays. Third, the SAC 7-35 comes with Sandia Aerospace’s Altitude In-Flight Monitoring (AIM). This technology warns the pilot anytime he deviates more than 100 feet from his selected altitude. Finally, the SAC 7-35 comes with multiple interface formats, so that it can connect to a wide range of avionics systems. The SAC 7-35 supports real time winds aloft, density altitude and digital outside air temperature. These avionics features help pilots calculate the best altitude for optimal cruising; safe landing and takeoff decisions at high altitude airports, and more effective monitoring of possible icing conditions.

The SAC 7-35 is available through Sandia Aerospace’s worldwide network of avionics shop and modification centers. For further information:
