The Voith-Schneider Propeller is a vertical-axis marine drive whose spinning blades change pitch continuously, letting a ship generate instant thrust in any direction, like a helicopter rotor underwater. Super-maneuverable, perfect for tugs and ferries.

Absolutely wild footage, this is a real world engine failure in a MD500 (Think Magnum P.I. helicopter) over Kauai, Hawaii out on a tour flight. You’ll probably have to watch this a few times but the video starts out with the helicopter under power and then the engine sound goes silent. The beeping you hear is the engine-out audio beep to inform the pilot that engine power has been lost. This maneuver that pilot is doing is called a Autorotation and the way to think about helicopter flight, the engine is turning this big fan (rotor blades) on top of the body and sucking in air from the top and projecting it downward to overcome the force of gravity. When engine power is lost, you experience a reverse in airflow because now gravity takes over and the air flow is coming from the bottom of the main rotor disk. The only thing the pilot can really do is to make sure the rotors keep spinning by changing the pitch of the rotor blades through the use of the “collective” which is a lever next to the pilot’s left leg and it only moves up and down. The pilot has to manipulate the collective during an auto rotation to make sure the blades keep spinning. If the pilot pulls up too much on the collective, the rotor blades will bite too much of air causing a resistance and slow the rotors down. If the pilot doesn’t pull enough collective.. the blades will speed up and potentially cause a catastrophic failure. The other control the pilot has is called the cyclic. This cyclic sits between the pilots legs and and manipulates individual pitch of the rotor blades to tilt the rotor disk aka “big fan” and make the helicopter go forward, backwards, left, right. So essentially in this type of emergency, you have to manipulate the controls in a delicate balance because no matter what, gravity is taking you to the ground because the engine is no longer producing power. The pilot did an outstanding job here given the geography and limited amount of flat terrain to put the helicopter on the ground. Thankfully it sounds like no souls were lost and only one injury according to a news report (see the link below)👇 Of course there is a lot more to helicopter aerodynamics but I’m trying my best to put this in simpler to digest terms. Big thanks to Combat Learjet for sharing and definitely worth a follow!

This technology has me curious. It's called Wind Sail Propulsion. It's still in the 1.0 stages IMO. It's kind of interesting though and could potential save on fuel costs to get things across the ocean. It harnesses wind energy to assist or, in some cases, serve as the primary means of propelling ships. Another technology is the Flettner rotor, which uses the Magnus effect—created by spinning vertical cylinders in a wind stream—to generate forward thrust. Unlike sails, the rotor is powered by its own motor, allowing it to generate propulsion even when wind direction is unfavorable. Do you see potential for this kind of technology? What kinds of potential problems could arise? 🤨

Austria-based startup CycloTech is developing flying aircraft powered by CycloRotor technology instead of traditional propellers. The company plans to build a four-seater air taxi with four CycloRotors, offering an 85 km range, 40 minutes of flight time, and a cruising speed of 150 km/h. Each CycloRotor uses rotating wings that continuously change their angle to generate thrust, allowing the aircraft to move precisely in any direction.

Gravity-defying robot! 🦎 VertiGo is a wall-climbing robot created by Disney Research and ETH Zürich that can transition between ground and wall. The robot can move on a wall quickly and with agility. VertiGo has four wheels, two tiltable propellers, and two tiltable propellers. One pair of wheels is steerable, and each propeller has two degrees of freedom for adjusting the direction of thrust. The choice of two propellers rather than one enables a floor-to-wall transition, thrust is applied both towards the wall using the rear propeller and in an upward direction using the front propeller, resulting in a flip onto the wall. P.S. Can you guess the year of development? 👀 ~~~ ♻️ Join the weekly robotics newsletter, and never miss any news →

This is what I’ve been saying for weeks on the podcast. It feels like there is no direction for Marvel. It feels like they are just spinning in different directions and no one is driving the bus. They need a clear direction for the universe.

THIS HELICOPTER HAS NO PILOT, NO GLASS, AND FLIES ITSELF No cockpit. No controls. No human inside. This isn’t a drone. It’s the world’s first fully autonomous uncrewed helicopter, built in Yeovil by Leonardo. No one’s flying it from a base. No joystick. It makes its own decisions mid-air. 8-hour flights, no rations, no rest. Just nonstop autonomous flight. There’s a giant space in the back for cargo, 5 rotor blades on top, and a tail like a classic chopper. Source: BBC

Helicopter Crash Hudson River Explained | New York How did this Bell 206 helicopter 2 Blade Propeller end up crashing with its own rotor blades slicing through the tail section and then separating from the main fuse sahlarge. We’ll break down the detailed timeline of events, along with several theories behind the crash and one stands out the most: This is Mast bumping—a dangerous event where the rotor hub strikes the mast, often caused by abrupt control inputs or low-G maneuvers. Not to Forget The Recorded Conversation of the Air Controllers until it Crashes AiTELLY Full Video Here The Bell 206 is a family of two-bladed, single- and twin-engine helicopters manufactured by Bell Helicopter Company. Introduced in the 1960s, Its siblings were widely used during the Vietnam War, as well as in military and law enforcement roles. According to the National Transportation Safety Board and various aviation safety databases, It's a pretty safe aircraft The accident rate is roughly 3.5 to 4.0 per 100,000 flight hours, which is typical for light helicopters in this class. #HelicopterCrash #HudsonRiverCrash #aitelly

Washington State Ferries (WSF) is once again struggling to keep its vessels afloat ahead of the crucial Seahawks-Rams game. Two large boats serving Seattle routes are currently out of service, leaving only 15 ferries when 17 are needed for full winter service, WSF said. The Seahawks' NFC Championship game, which will determine a spot in the Super Bowl, is happening at Seattle's Lumen Field on Sunday. One of the two large ferries that's out of service is the Wenatchee, which hit a log and bent a propeller during foggy weather on Wednesday. The vessel, which is used on the Seattle-Bainbridge Island route, can carry 202 vehicles. It's one of the largest ferries in the WSF fleet.

🚨THE KING OF HEAVY LIFT JUST ENTERED THE SKY Watch this machine carefully. In slow mo… That is a U.S. Marine Corps CH-53E Super Stallion tearing through the sky like a steel thunderstorm. Three General Electric T64 engines screaming. Seven massive rotor blades carving the air. Nearly 80,000 pounds of flying American engineering. This isn’t a helicopter… It’s a flying freight train. The CH-53E can lift 36,000 pounds of cargo and haul Marines, artillery, vehicles, or battlefield supplies wherever they are needed. Bridges. Mountains. Cities. Ocean assault zones. It doesn’t matter. When the Super Stallion arrives, it brings the logistics power that wins wars. Watch the rotor wash kick up dust as it drops low over the town. That’s the sound of raw mechanical authority. This aircraft has been the backbone of Marine heavy lift for decades… Delivering troops into combat zones… moving artillery… hauling vehicles… and resupplying forces where no truck or ship can reach. People talk about fighters like the F-22 and F-35… But wars are won because machines like this move the weight of war itself. The CH-53E isn’t flashy. It’s relentless. And when the Marines need something moved… This monster answers the call. #SilentMajoritySpeaks #AStoneGroove

Eric Hartman with a 3 for 5 day with a double and 2 singles (got thrown out trying to stretch for a second double) After hitting .299 in April and .296 in May, he is SCORTCHING to a .414 in June with 12 hits in 29 at bats and the exit velos continue to stay impressive. I have been super impressed with his feel for the zone and limited chase until he gets a pitch he can drive.

🇩🇪 Nuclear submarine commanders train their entire careers to remain invisible. This helicopter exists to find them. The NH90 Sea Tiger is Germany's new naval helicopter and it hunts submarines using 3 simultaneous methods: 1. 360-degree radar and infrared cameras scanning the surface for periscope exposure 2. ⁠Active dipping sonar lowered on a cable that bounces acoustic pulses off metal hulls underwater 3. ⁠Sonobuoys, a deployable grid of floating microphones that listen for reactor hum and propeller vibrations Onboard computers use this data to calculate the submarine's exact depth, speed, and heading, then the helicopter launches a lightweight torpedo that continues the hunt autonomously. Submarines have historically been a weapons system that required either another submarine or a dedicated warship to neutralize. The Sea Tiger changes that calculus by putting submarine-killing capability into a helicopter that can be deployed from almost any naval vessel. Nowhere to hide in modern warfare, the tech has gotten too good. Source: Defence Dec YT0

A U.S. Border Patrol K9 named Boo was bitten by a rattlesnake while patrolling the rugged Otay Mountain Wilderness. Boo’s handler quickly called for help, and within minutes, agents with CBP Air and Marine Operations airlifted the injured dog by helicopter to a veterinary emergency hospital in La Mesa. The helicopter touched down near the intersection of Grossmont Boulevard and Jackson Drive, surprising residents and drivers who weren’t sure what was happening. Fortunately, Boo received antivenom and IV fluids in time and is now under observation. Officials say he is stable and recovering. Yay Boo!!!!! 🥰🥰

"MAH" takes off for the first time. MAH is a new, dedicated attack helicopter designed for the South Korean Marine Corp. 20mm triple barreled chain gun, Taipers missiles, France Mistral, proven platform, latest avionics..that sounds promising. I should call this Korean Hind. It is a modified attack version of the KUH-1 "Surion" and MUH-1. This latest medium multipurpose platform has been mass-produced, is still in production, and is highly digitalized. As you may have guessed, MAH can transport troops, too. The MAH's avionics are also influenced by LAH. The ROK Army uses the U.S. Apache and Cobra attack helicopter. It looks good than I expected. Perfect for the Marine.

An island nation like Scotland must have a thriving commercial shipbuilding industry. The SNP gave away a £150 million contract for 7 small ferries to Remontowa in Poland last year, and is now stalling on directly awarding a 4 vessel contract to Ferguson Marine first announced four months ago, putting hundreds of shipbuilding jobs at risk as the shipyard runs out of work soon. For a nationalist party, they have a poor understanding of the national interest.
