Though I’m a huge X-Files fan, I’ve never gone in for some of the more esoteric UFO theories. But one thing I do love is solving engineering problems, and the problems posed by a flying saucer-shaped aircraft are real humdingers. Boundary conditions of stability and structural integrity are imposed by designs with a specified physical envelope and performance goals. So I’m really digging this article from Wired about US Air Force Project 1794, in which the problem of how to build a flying saucer was actually explored. From Wired:
Officially, aliens have never existed but flying saucers very nearly did. The National Archives has recently published never-before-seen schematics and details of a 1950s military venture, called Project 1794, which aimed to build a supersonic flying saucer.
The newly declassified materials show the U.S. Air Force had a contract with a now-defunct Canadian company to build an aircraft unlike anything seen before. Project 1794 got as far as the initial rounds of product development and into prototype design. In a memo dating from 1956 the results from pre-prototype testing are summarized and reveal exactly what the developers had hoped to create.
The saucer was supposed to reach a top speed of “between Mach 3 and Mach 4, a ceiling of over 100,000 ft. and a maximum range with allowances of about 1,000 nautical miles,” according to the document.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
