Morse stresses that there are two very different kinds of threat, depending on whether the object hits the airframe or, in the case of jet airliner, goes into one of its turbofan engines.
In a collision with the airframe, the danger scales with the relative velocity of the two objects, because the amount of kinetic energy released on collision is proportional to the square of that velocity. But for a turbo engine, Morse says “it’s an entirely different scenario.” In this case, the relative speed of the colliding objects doesn’t matter so much. What’s key is the power level the engine is running at, because that controls how fast the fan blades are spinning, which in turn controls the speed at which the blade hits the incoming object…
…If a really tiny drone were to go into a turbofan engine, explains Morse, it might slip between the fan blades and do little damage. But a typical drone of the size we are discussing, several tens of centimeters across, is too big for that to happen. “In that case, it’s going to be more like a bird strike,” says Morse.
Welcome to drone day on the Adafruit blog. Every Monday we deliver the latest news, products and more from the Unmanned Aerial Vehicles (UAV), quadcopter and drone communities. Drones can be used for video & photography (dronies), civil applications, policing, farming, firefighting, military and non-military security work, such as surveillance of pipelines. Previous posts can be found via the #drone tag and our drone / UAV categories.
8-6-2021 (August 6, 2021) is the Snakiest day of the year and it’s also this year’s CircuitPython Day! The day highlights all things CircuitPython and Python on Hardware. See you there!
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
