HELICOPTER FOR EXTERNAL CARRIAGE OF CARGO Russian patent published in 2005 - IPC

FIELD: aeronautical engineering.

SUBSTANCE: proposed helicopter is provided with differential autopilot with helicopter attitude sensors, computer and combined control units. Helicopter is also provided with collective-pitch control lever, longitudinal and lateral control stick, radio altimeter, cargo longitudinal and lateral deflection sensors, instrument board with indicators and electronic displays. Besides that, helicopter is provided with precision hovering system which includes onboard TV tracking unit connected with display-indicator of precision cargo setting system, reception equipment of satellite navigational system, cargo setting point coordinate selector, preset coordinate correction unit connected with coordinate setting joy-stick and trajectory control computer -onboard digital computer. Onboard digital computer includes computer for automatic control of coordinates of preset point and computer of logics of joint operation of manual and automatic control, as well as cargo stabilization computer. Trajectory computer is connected with satellite navigational system, radio altimeter, cargo setting point coordinate selector, preset coordinate correction unit by means of information interface unit and with onboard TV tracking unit through display-indicator of precision cargo setting system. Input of cargo stabilization computer is connected with cargo longitudinal and lateral deflection sensors. Respective inputs of logic computer of joint manual and automatic operation are connected with helicopter longitudinal and lateral control stick and cargo stabilization computer; its output is connected with autopilot computer.

EFFECT: enhanced automation of helicopter; improved observation systems; enhanced efficiency of cargo transportation.
