Air Force pilots test electric 'flying taxi' The U.S. Air Force is looking at all-electric transport options too. Four Air Force pilots remotely flew a Joby electric vertical takeoff and landing (eVTOL) aircraft recently. They were the first Air Force personnel to assume remote pilot-in-command responsibilities and transition flight for the eVTOL, preparing the Air Force for delivery of aircraft to Edwards Air Force Base in California.

WWII Engineering: The saga of the bird-brained bombers During World War II, the National Institute of Standards and Technology (NIST) was among those working intensely to develop guided weapons to help the Allies win the war. But before the advent of satellites and GPS, laser targeting, or even radar, how would one guide a bomb? Why, trained pigeons, of course.

Researchers 3D print a better mini vacuum pump Researchers at MIT rethought the design of a peristaltic pump from the bottom up, looking for ways they could use additive manufacturing to make improvements. They used one pass on a multimaterial 3D printer to make a mini device that can create and maintain a vacuum that has an order of magnitude lower pressure than a so-called dry, rough pump, which doesn't require liquid to create a vacuum and can operate at atmospheric pressure.

Porsche's top seller: Cayenne SUV gets more more more for 2024 Porsche's top-selling vehicle for 2022, the Cayenne, was responsible for just under one-third of all Porsches sold overall last year. To that end, Porsche is sticking with a real winner and has upgraded the third generation of the Cayenne with comprehensive changes to the powertrain (including new V8 options), chassis, design, and in-car technology.

Slimmest enclosure air conditioner on the market! Seifert's SlimLine Series of enclosure air conditioners integrates unique technologies -- maximum power-to-size ratio and a mounting of merely 4.5 in. inside-cabinet depth -- making the it the slimmest air conditioner in the market. The condenser is specifically designed to maintain performance without maintenance in environments where dirt and dust are present. Cooling capacity: 1,090 to 5,120 Btu/hr. Lots of model options.

What they didn't teach you about fittings in engineering school Do you know why an old standard "Christmas-tree" barbed fitting may not be your best choice for your miniature fluid power application? Experts at Beswick Engineering run through the common types of fittings used in these smaller pneumatic applications, along with thread sizes and seals to help you make the correct choice. They also touch on pressure and temp ranges, chemical compatibility issues, rigid and flexible lines, and the ease of assembly and maintenance.

Tech Tip: 5 considerations to optimize frameless motors in aerospace and defense applications Engineers prefer to specify motors that are readily available and affordable, yet commercial off-the-shelf motors may not meet the needs for a successful aerospace and defense (A&D) program. Higher shock loads. Optimized motor windings. A larger through-bore aspect ratio. How do you achieve these and other specialized motor attributes on a rapid development schedule that requires cost-effective production and a reliable supply? Learn more from Kollmorgen. Good info here about customization.

Part finishing: New smart cobot solution sands, grinds, and more Kane Robotics has launched its first collaborative robot (cobot) solution, the GRIT™ cobot. Developed by aeronautics and composite experts, GRIT dramatically improves productivity, reduces health risks, and solves labor shortages for aerospace maintenance, repair, and overhaul (MRO) companies and other types of manufacturers. This reconfigurable cobot comes in three sizes and works alongside humans to perform labor-intensive sanding, grinding, and polishing for materials removal within any size and type of manufacturer. Average ROI is 6 months. Watch a video of how it works.

Couplings solve misalignments more precisely with targeted center designs ALS Couplings from Miki Pulley feature a simplistic, three-piece construction and are available in three different types for more precisely handling parallel, angular, or axial misalignment applications. The key feature of this coupling design is its center element. Each of the three models has a center member that has a unique and durable material and shape. Also called a "spider," the center is designed to address and resolve the type of misalignment targeted, thereby reducing reaction loads resulting from the misalignment. Ideal for unidirectional continuous movement or rapid bidirectional motion.

Will a hydrofoiling center console boat fly in America? Swedish boat builder Candela aims to electrify America's No. 1 boat segment: center consoles for fishing, families, and watersports. The company's 29-ft C-8 CC model flies on computer-guided hydrofoils, which are underwater wings that enable it to soar above the waves using 80% less energy than conventional V hulls.

| Everything you need to know: Electric vehicle tires | |
What happens if you put a "regular" car tire on an electric vehicle (EV)? Engineering Explained's Jason Fenske covers that and more when he gets deep into why EV tires are different than internal combustion engine (ICE) car tires due to weight, efficiency, noise, and torque demands and other characteristics. You always learn something from a Fenske video.
