Setting up a vtol in mission planner

Image
Introduction Setting up a vertical take off or landing (VTOL) uav is one of the more complex aspects of mission planner, for programming a pix hawk flight controller. The vtol that will be set up in this blog is a 2.5 meter wingspan, custom quad rotor, with all four motors tilting uav. Figure 1. A screen capture of the firmware installation page of mission planner  To begin install arduplane on your pixhawk, using the install firmware page in mission planner, figure 1 shows the pop up window that should appear. Next once the firmware is installed go through each of the settings of the mandatory setup, including the accelerometer calibration, compass calibration and the radio calibration, but skip the servo output for now. The next step is going to the full parameter list under the configuring and tuning tab, and enable Qplane, which stands for quadplane, and allows for all the vtol settings to be shown. Then the frame style and setup has to be configured, these have t...

Designing a Vtol Mechanism from scratch

Image
Introduction A project that I have been working on needed a Vertical takeoff or landing (VTOL)  tilt mechanism for the the front 2 motors, so here is how I went about designing and testing it. It can be challenging to hand launch a twin motor plane as you have to worry about both prop disc areas, while managing controls, and adding a vtol system can allow for operations where a wheel based takeoff is not a possibility  The specifications of the propulsion system are a Emax 2213-935KV brushless motor, that spins a 8045 prop, with a spider 20apm opto esc, using a 4 lithium polymer cell battery. This power systems is typically used in quad copters such as a dji flamewheel 450. The servos for tilting the motor varied depending on the design of the tilting mechanism. Figure 1. A dji flamewheel 450 quadcopter, with a propulsion system similar to the VTOL's system Goals  The goals of this project was to be able to develop a vtol tilt system for a uav that ...

Installing Mission planner Hardware in a fixed wing aircraft

Image
Project overview To get the benefits of mission planner on a asw28 2.5m motor glider, a few important hardware setup details will allow for a better preforming aircraft. This installation of a mission planner based flight controller will allow for autonomous soaring, where the aircraft automatically senses lift and trys to stay in that thermal. Another feature that mission planner allows for is return to home, and with a large sailplane, some thermals can take them out of sight. Figure 1. Stock asw 28 sailplane Aircraft current status: The aircraft is currently a stock ASW 28 v2, it has a motor and esc/bec combo, with 6 servos. The 6 servos actuate the ailerons, flaps, rudder and elevator. With the independent servos for the ailerons and flaps, it allows for the aircraft to use crow on landings. Crow is where the ailerons both move upward and the flaps drop down, this causes an immense amount of drag, which aides in the landing of the aircraft. Hardware to be installed To a...
