Abstract

We participated in the 17th Flow Dream Contest as the team name "MeasLab" and were honored to receive the Best Prize. We would like to introduce our work. The theme of this year's contest was "Let's play with flow." To achieve this, we decided on the concept of a "flight simulation game of micro air vehicle (MAV)." First, the contents of the flight simulation game are explained in Fig. 1. The left side of the figure shows our work, which consists of a desktop wind tunnel, a NACA 0012 airfoil, and a display. A game user can adjust the angle of attack with the controller and changes the pressure distribution around the airfoil. Flight simulation is performed on the small single-board computer (Raspberry Pi), which is based on the sensor output mounted on the airfoil. The calculated flight altitude is displayed on the monitor in real-time. Blue and red gates are also displayed, and when the MAV passes through a gate, a user gets points according to the color. The user is required to control the flight altitude to accurately pass through the gates. Second, we explain design and devices. Figure 2 shows an overview of the game device. The flow is generated by a desktop wind tunnel which is composed of a contraction, a honeycomb, an observation area, and a PC case fan. Figure 3 shows the observation area, the display, and the NACA 0012 airfoil with two pressure sensors. The pressure is measured through holes on the upper and lower airfoil surfaces. On the left side of the display, there is a blue led array to visualize the score.  At the bottom of the display, there is a red led array to visualize the freestream velocity.
