VF 50P composite wing vertical takeoff and landing unmanned aerial vehicle

The composite wing layout combining fixed wing and quadcopter solves the problem of vertical takeoff and landing of fixed wing unmanned aerial vehicles in a simple and reliable way, combining the characteristics of long flight time, high speed, and long distance of fixed wing unmanned aerial vehicles with the function of vertical takeoff and landing of rotary wing unmanned aerial vehicles. This drone platform can operate smoothly in complex terrain and densely populated areas such as mountainous regions, hills, and jungles, greatly expanding the application range of drones and making it an ideal choice for industrial grade drones.

Astronomical pentameter

The Astronomical Quintant, also known as the Astronomical Goniometer, is an ancient astronomical instrument used to measure the elevation angle of celestial bodies. It consists of a quarter arc and a movable cursor. The principle of the astronomical pentameter is based on the method of triangulation. When the observer raises the astronomical pentameter towards the sky, the cursor can move to align with the line of sight of a celestial body. Surveyors can determine the elevation angle of celestial bodies by reading the scale on the cursor. Usually, the scale on an astronomical pentameter is spaced at intervals of five degrees, hence it is called a pentameter.
