The Army Product Manager Apache Sensors in Huntsville is working
with the Armament Research, Development and Engineering Center
at Rock Island, Illinois, to modernize the Apache Integrated Helmet
And Display Sighting System (IHADSS). The monocular IHADSS has
a field of view 40 degrees horizontal by 30 degree vertical. It shows
the AH-64 pilot and co-pilot/gunner pilotage and targeting imagery
with symbology, and it aims the Apache gun.
Ongoing engineering development aims to replace the obsolete
cathode ray tube (CRT) in an ESA helmet display unit (HDU)
with a brighter organic light-emitting diode (OLED) flat panel
display made by eMagin. OLED technology provides higher
brightness, contrast and resolution than CRT displays with less
power required. The thick power cable run to the Apache helmet
gets notably thinner and lighter with OLEDs. The monochrome
OLED HDU completed critical design and test readiness reviews
successfully and should finish development in 2019. Program
Manager Apache Sensors is meanwhile exploring a follow-on
color OLED replacement.
