AFRL Tests Show LADAR Can Potentially Remedy Helicopter Brownout Problem Published Aug. 29, 2007 By Munitions Directorate AFRL/MN EGLIN AIR FORCE BASE, Fla. -- Air Force Special Operations Command incurs significant damage to aircraft and--even worse--loss of life as a result of helicopter brownout, a problem wherein dust recirculated by the rotorwash causes pilots to lose visual cues during takeoffs and landings in dry regions. AFRL engineers identified LADAR (laser radar) technology as a sensor technology capable of providing landing zone situational awareness. AFRL engineers conducted several experiments to assess the potential capability of a LADAR system in helicopter landing scenarios. They collected high-resolution three-dimensional imagery that provides immediate feedback to the pilot for obstacle avoidance and ground slope indication. In addition, while testing in a controlled dust chamber, the engineers demonstrated a see-through imaging capability using a variety of techniques. Loss of situational awareness puts pilots under extreme stress during brownout conditions. Field test results indicate that LADAR technology can offer an excellent solution to the helicopter brownout problem. Department of Defense rotorcraft pilots are giving the LADAR system a strong endorsement after seeing the test results.
