PROJECTS

Ship-to-Shore Connector (SSC)

IDI was selected to provide an Electro-Expulsive Ice Protection System (EPIPS) on the Textron Ship to Shore Connector. The SSC will provide a modernized means for the Navy and Marine Corps to land at more than 80 percent of the world's shorelines for the next 30 years. EPIPS is an acceleration based deicer for ice protection on ships and aircraft. This system provides an efficient low power solution for metal and composite applications where sufficient electrical power is not available.

RV-10 System

An EPIPS kit is now available for experimental aircraft owners to provide deicing on the main wings and tail section. The kit includes a Deicing Control Unit, Actuator Electronics Module, Actuator Harness, I/O CAN Harness, Deicing Power Switch, and Power Cable. Total Deicing System Weight is approximately 35 lbs. Custom deicing system solutions are also available upon request.

Emerging Techonologies

Airborne Icing Measurement System (AIMS)

AIMS is a small optical based sensor that measures the liquid water content, drop size, density and phase of clouds. The innovation is a new capability for measuring cloud properties in-flight.

Low power infrared lasers illuminate the interior of the cloud and the resulting backscattered signal is analyzed in real-time to determine cloud properties. Using serial communications, the cloud property data is saved to an on-board data logger and can be transmitted to a ground station via RF link.

Shape Memory Alloy Deicer

The Shape Memory Alloy (SMA) Deicer uses cutting edge technology to autonomously detect and remove ice from helicopter blades. This deicer provides an efficient solution for rotorcraft applications providing superior erosion resistance. IDI developed the system in collaboration with the NASA Glenn SBIR program.

The deicer is made from a durable Nickel Titanium alloy that has the ability to change shape when subjected to an appropriate temperature change. The deicing action is analogous to a conventional thermal expansion except that it is enhanced to the levels needed to remove ice. It can be activated by electrical current or can be passively powered from heat transfer energy due to the formation of the ice itself.

Material processing techniques developed at IDI have produced unique SMA material configurations capable of satisfying rotorcraft deicer performance requirements. Energy estimates indicate substantial savings over existing electro-thermally powered deice systems, with much improved durability and erosion resistance.

Acoustic Wiring Diagnostic System

This system uses piezoelectric sensors to listen for wire chafing and arcing events without removing or disconnecting the wires under evaluation. It operates continuously in-flight so that intermittent wiring fault conditions can be detected as they happen.

 

Noise generated by the chafing in-flight is statistically related to structural vibrations, and the chafing source located through signal correlation techniques. Trend analysis data is logged to enable pro-active maintenance prior to catastrophic failure. Flight ready hardware and software was developed and flight tested on an H-53 helicopter.

Low Cost Wind Sensor

Under an Army SBIR, IDI is developing a compact laser based crosswind sensor for incorporation into shoulder fired weapon systems. A ballistic firing solution must take into account variability of the wind. Current anemometers solutions are expensive, large, heavy, and consume too much power for small arms applications.

 

The optical sensor has an advantage over conventional anemometers of being able to detect crosswinds even when behind cover, and at very low cost using all semiconductor integrated VLSI technology.
