Title: Innovations by Sam Ok Koo in Aerospace Technology

Introduction

Sam Ok Koo is a notable inventor based in Daejeon, South Korea. He has made significant contributions to the field of aerospace technology, particularly in the development of systems for aerial vehicles. With a total of 2 patents, Koo's work focuses on enhancing the performance and control of flight vehicles.

Latest Patents

One of Koo's latest patents is a system for controlling the propeller and rotor RPM of an aerial vehicle that has multiple power devices. This innovative system includes a collective pitch angle command generating unit that produces a command based on thrust control inputs from a pilot or an automatic controller. Additionally, it features a disturbance factor compensating unit that generates an RPM compensation electronic speed control (ESC) command to correct any RPM errors. The final ESC command is derived from the collective command input and the RPM compensation ESC command, ensuring that the RPMs of motors in a flight vehicle with multiple propellers and rotors are maintained consistently.

Another significant patent by Koo involves a high-performance tilt rotor aircraft where the nacelle tilt angle and flaperon angle are mechanically interlocked. This design allows for the nacelles, which house the rotors, to rotate based on the flight mode—whether for forward flight or vertical take-off and landing. Each main wing of the aircraft is equipped with a flaperon that rotates in conjunction with the nacelle, enabling a coordinated change in the nacelle tilt angle and flaperon angle.
