A study on a flight display using retro-reflective projection technology and a propeller

The head up display (HUD) is becoming increasingly common in the aerospace field because it has many benefits such as enabling operations in poor visibility and improving flight safety. The HUD is a kind of augmented reality display that enables a pilot to observe the scene outside the cockpit while simultaneously viewing an artificial image of flight information. However, the HUD is too expensive and heavy for light airplanes. In this paper, we propose a new method to combine real and artificial images using Retro-reflective Projection Technology and rotating objects, and we apply the method to an airplane with a single propeller to compose a simple HUD. In this report, we also describe the developed system and preliminary experimental results.
