🚨 THIS DRONE SWAPS NORMAL PROPS FOR 3D-PRINTED DUCTED FANS. Those swirling white shrouds enclose the blades completely. Ducted designs cut tip vortices, boost low-speed thrust, and make the whole craft quieter and safer. Experimental aerodynamics you can actually fly.

Mostly a hover and low-speed machine. The shrouds boost static thrust, cut tip losses, and add safety and quietness, but in forward flight the added drag usually cancels those gains and an open prop is more efficient.

Yes but you add no link/url to original youtube vidéo... Source ?

Actually, I don't know about that I am sorry for that

Are the shrouds paying off in forward flight too, or is this mostly a hover machine?

I think it can play tennis by itself. Someone who owns this please try

how much quieter

The Cosmos Network's profile picture
The Cosmos Network2 days ago

About 3–7 dB quieter in typical tests (roughly half the sound pressure at the high end), mainly from reduced tip vortices, though some designs show little net gain or even higher broadband noise.

Thrust to weight?

The Cosmos Network2 days ago

No exact number published. It flies and hovers easily, so TWR is comfortably above 1:1 (typical controllable multirotors aim for ≥2:1). Ducts usually add 5–20% static thrust versus open props of the same size, but the extra weight and drag mostly help only in hover.

Pretty amazing... but what about in lower performance setups? Smaller motors etc.🤔

To further reduce drag, you can also try giving the surfaces of critical parts a texture like that of a golf ball.

Bob Lazar allegedly watched people fly a UFO at Area 51. “They knew how to fly it.” “The craft had a corona discharge glow on the bottom and lifted off silently up into the sky … ” And it had one shocking, anomalous effect that still perplexes him to this day: As Lazar watched, his supervisor Dennis Mariani told him to go stand directly underneath the craft. “I walked out underneath it and … I looked up, and I couldn’t see the craft.” “I thought it flew away.” “Then he said to come back, and I walked back.” “I see the edge of the craft.” “If you move, you can see it, and if you walk underneath it, you can’t.” “So you can clearly see it’s bending the light.” “You can see the sky above the craft, so you can see that it’s in its little envelope.” Lazar was also convinced that someone was actually inside the craft as it flew. “I did notice there was a … VHF radio.” “And they’re in communication.” “It made me almost positive that there was somebody in the craft.” He heard a voice coming “from the VHF radio, but presumably coming from the craft.” “They must have had some instrumentation set up in the craft, because he was monitoring something.” “I was stuck on the fact that, how is a radio wave of getting into the craft?” “This doesn’t even make any sense.” “It should be distorted by the gravity wave going around it.” “Clearly, they’ve had a lot of time with this craft already.” “It could have been decades for all I know.” “They knew how to fly it.” “These guys were somewhat proficient with it.” Jesse Michels asked Lazar if that means that we actually have “alien reproduction vehicles, or UFOs that humans can fly?” Lazar: “I do not think so, no.” Michels: “So you think we can test these things and use them in rudimentary ways, but we don’t understand how they work?” Lazar: “It’s like the analogy … you can go back to the 1800s and drop off a motorcycle with the keys in it.” “If you tinker with it long enough, someone’s gonna turn the key and it’s gonna start.” “Eventually … they’ll become proficient at driving it.” “But when it runs out of fuel, we’re done.” “And … they can’t even make that plastic fender.” “I think that’s where we are [with UFOs].” “We had some knowledge of that, but I think if we had developed that technology, we would’ve absolutely already seen it.” Jesse Michels American Alchemy

😎🤌 According to Bob Lazar, UAP operate using a gravity wave-based propulsion system that distorts space-time rather than using conventional thrust 👽🛸 The craft generate power and gravity waves through a reactor fueled by a stable isotope of Element 115. In the reactor, Element 115 is bombarded with protons, briefly becomes Element 116, decays, and releases small amounts of antimatter. This antimatter annihilates with matter to produce enormous energy (near 100% efficient), which powers the craft and also creates a unique Gravity A wave (a micro-scale gravity field Lazar says is an extension of the strong nuclear force). This Gravity A wave forms around the reactor at the top of the craft. A waveguide channels it downward into three gravity amplifiers arranged in a triangle at the base. These amplifiers run at full power at all times and can phase-shift the wave (0° to 180°) to control direction and strength. By focusing and amplifying the gravity wave, the craft creates a powerful, localized gravitational distortion: - It bends/warps space-time in front of the vehicle. - This effectively pulls the destination toward the craft (instead of pushing the craft forward through space). Operation modes: - Omicron mode (hovering/low speed): Amplifiers point downward → craft balances/sits on its own gravity field (explains the characteristic wobble/bobbing seen in many videos). - Delta mode (high speed/travel): Amplifiers point forward → extreme space-time warping for rapid movement. Key effects: - No inertia (occupants feel no acceleration). - Time dilation near the craft. - Optical distortion (gravity lensing can make the craft appear blurry, shimmering, or invisible). In essence, the craft "falls" toward its target by warping space ahead of it, allowing extreme speeds, sharp turns, and interstellar travel without conventional motion or time dilation issues for the occupants.

CSS variables are live and they are POWERFUL. Now Live on Product Hunt 🚀 ➡️ Create a design system "So you can stay consistent and build much quicker." Define global styles like colors, gradients, sizes, and box shadows. ➡️ Use your variables everywhere "So you never have to manually enter a border color again." You're not limited to just sizes, colors, and font families. Use variables in gradients, box shadows, transforms, and more! ➡️ Start with libraries like Open Props, expertly crafted CSS variables "So you can use a tried and true system, and so we can standardize our Projects." Because there are no abstractions, you can use existing CSS variable libraries like Open Props, an expertly crafted library of CSS variables, and the recommended starting point in Webstudio. ➡️ Create complex micro-interactions "So when you hover a link, you can change any children's styles." CSS variables go beyond reusability! You can define variables anywhere in the navigator, such as on a link, and modify the variables on hover. Then, you can use those variables on the children to create complex micro-interactions! ➡️ Design and build simultaneously "So when deciding that perfect border color, you can arrow through all your options." Experimenting on the canvas just got a whole lot better. Now, you can arrow through your variables and see them rendered on the canvas to see which works best. ➡️ Change variable by breakpoint "So you can make the variables look great, no matter the screen size." CSS variables in Webstudio use the same UI as the rest of your styles, enabling breakpoints to work the same way. ✨ Building with design systems gives a HUGE boost in speed, consistency, and maintainability.
