A modem integrated helmet system (IHS) consists of a helmet shell, a Helmet Mounted Sight (HMS), two Image Intensifier Tubes (IIT) and two Cathode Ray Tubes (CRT) with an optical system including combiners to present the images binocular. Additional symbology can be superimposed to the CRT- or IIT-image. An IHS is a further development of a Helmet Mounted Display (HMD) to cope with more demanding requirements regarding ergonomics and operability under adverse visual conditions. The HMS can steer a sensor platform with a thermal camera or an air-to-air missile system. The main helicopter (HC) requirements on such a system are: -) human factors -) fit of helmet including optimized centre of gravity(CG) and weight -) optimized day, twilight and night optical modules -) large exit pupil, good transmission of the optical path and a large adjustment range -) good geometrical resolution / Modulation Transfer Function (MTF) with a large Field of View (FOV) -) high focussing range of the IIT and a good S/N ratio below 1 mLux -) CRT automatic brightness and contrast control with a good readability on day time -) flight symbology presentation for one or two eyes -) good static and dynamic HMS-accuracy with a large Head Motion Box (HMB) -) NBC and Laser protection compatibility MBB and the German Army Aviation Corps have made last and this year ground and flight trails with an Integrated Helmet and a HMS on a PAH 1 respectively a BK 117 helicopter. The paper will present IHS requirements for HC application and some test results.
