![]() In front of each seat is a cyclic, which looks like the control stick in an airplane. You alter lift by changing the pitch of the blades while making sure they turn at a constant, safe speed. Note that on a helicopter, you do not alter lift by making the main rotor spin faster or slower. Increasing rotor pitch also increases drag, which must be compensated by increasing throttle to maintain a constant target rpm (the green area on the dual tachometer for engine and rotor revolutions, at the upper left). The collective also has a twist grip controlling the throttle. Raising it increases the pitch of all the main rotor blades the entire way around, increasing lift. It looks like the lift-handle parking brake in some cars. Unlike most later helicopters, the primary pilot of the Bell 47 sits on the left. To understand what both rotors do, I need to explain the controls in the cockpit. READ MORE: A Fanciful Flight in the ‘Spruce Goose’.The same engine drives both the main and tail rotor, via a cylinder-shaped transmission gearbox above the engine. Earlier Bell 47s used a less-powerful Franklin piston engine. This is a Bell 47G, so the engine is a single Lycoming 6-cylinder, air-cooled piston producing 280 hp that is also used in some versions of the Beechcraft V-Tail Bonanza. The Bell 47’s fuel tanks varied by model, but the two perched here each hold 30.5 gallons for a maximum range of 214 nm (246 sm or 396 kilometers). The Bell 47 has an empty weight of 1,893 pounds, about the same as a Volkswagen Beetle. The cockpit is made of sheet metal, with a plexiglass bubble windshield, and the tail is composed of exposed steel tubes. The construction is bare bones, nothing fancy. The helicopter’s height, to the top of its rotor mast, is 9 feet, 3 inches. The span of the main rotor is 37 feet, 2 inches. The fuselage of the Bell 47 is 31 feet, 7 inches from cockpit windshield to tail. First, let’s look at the tricky, bug-like aircraft that became their most recognizable symbol, the Bell 47. I’ll talk about MASH units, and the 8209th in particular, in a bit. The unit was equipped with Bell 47 (H-13) helicopters, which were famously featured in the opening credits of the long-running comedy-drama. As a result, it was home to the 8209th Mobile Army Surgical Hospital (MASH), one of several units on which the fictional “4077th MASH” of TV fame was based. It was close to some of the toughest fighting late in the Korean War, including battles at Heartbreak Ridge and Bloody Ridge. It’s the winter of 1952, and this H-13 is parked in the Haean Basin, an oval-shaped valley just south of today’s DMZ between North and South Korea-dubbed the “Punchbowl” by American troops. Army, which designated it as the H-13 Sioux. However, improvements to Young’s Model 30 by late 1945 gave rise to the Model 47, a product Bell Aircraft viewed as marketable. ![]() Army, which saw limited search-and-rescue operations in the Burma Theater. In 1943 Igor Sikorsky sold the R-4 helicopter to the U.S. The Germans created a number of prototypes during the war. It was not the first helicopter to be developed. Over the next few years, the small engineering team led by Young developed a helicopter, the Model 30, capable of controlled flight. ![]() In 1941, he took his models to Bell Aircraft in Buffalo, New York, and the company agreed to work with him in developing full-size prototypes. READ MORE: Canada’s Rugged, All-Metal National AirplaneĪt his family’s farm outside of Philadelphia, Young spent 12 years conducting private experiments with model helicopters until he could reliably get them to fly.At that time, the development of helicopters was a field full of eccentrics, and Young fit the profile of the lone oddball genius. Drawn to philosophy, Young wanted to tie his more esoteric interests to the solution of elusive practical problems, and the one that intrigued him most was the helicopter. Bell was known for producing highly innovative if not necessarily successful airplanes during World War II, most notably the tricycle-gear P-39 Airacobra fighter.īut the story of the first Bell helicopter begins in 1927, when a man named Arthur Young graduated from Princeton University with a degree in mathematics. The Bell 47 was produced by Bell Aircraft, founded by Larry Bell in 1935. Today in Microsoft Flight Simulator 2020, I’m in Korea to fly the Bell 47, the iconic chopper from the TV show M*A*S*H and the first helicopter to be certified for civilian use. ![]()

On the left side of the image you see the tip of the shoe within the 3D view.The image to the right illustrates the mapping from a flat image to the surface of a mesh object: Since faces are flat, projecting flat images on them is easy. Remember the basic building block of mesh objects are Faces. The image content is then mapped to the surface of the 3D object. One very common method to add color and structure (aka texturize) is by using 2D images (textures). We have to tell Blender in more detail how we want the different parts to be colorized. We have to provide hints where these parts are located on the model.

About 60 percent of NASA positions are in professional. ![]() NASA Television will provide complete coverage Tuesday, March 1, as three crew members depart the International Space Station, including NASA astronaut Scott Kelly and cosmonaut Mikhail Kornienko of the Russian space agency Roscosmos the station’s first one-year crew. ![]() "On my last flight, which was six months long, it seemed to take about six months for me to start to feel really back to normal in that regard," Scott Kelly said. In March 2016, the average NASA salary was 119,665. The pair will land March 1 after spending a total of 340 days in space. Scott Kelly said he feels pretty good at the moment, though he's still not fully back in the swing of Earth life, which is much less structured and regimented than life aboard the orbiting lab. Determining how Scott Kelly and Kornienko fared psychologically and physiologically during their 340 days in orbit should help keep future Red Planet pioneers safer and healthier, NASA officials have said. After almost 200 days in space it is time to return to planet Earth for ESA astronaut Thomas Pesquet, JAXA astronaut Aki Hoshide and NASA astronauts Shane. The main goal of the one-year ISS mission, and the associated " twins study," is to help lay the foundation for crewed journeys to Mars, which NASA hopes to pull off by the late 2030s. Sellers had served as acting director of the Earth Sciences Division at NASAs Goddard Space Flight Center in Greenbelt, Maryland. The board then invites a small group of the most highly qualified candidates for interviews at NASAs Johnson Space Center in Houston, Texas. "So, for the last year, while he was in space, I was the lowest-paid federal government employee," Mark Kelly said. NASA’s Astronaut Selection Board reviews the applications (a record-breaking 18,300 applications in 2016) and assesses each candidate’s qualifications. Kelly and Kornienko will return to Earth on Soyuz TMA-18M in March 2016. "So I was all excited - how much am I going to get paid?"īut the going rate turned out to be minimum wage, he added. An astronaut can make anything between 65,140 to 142,000 annually. "But a month later, they come back and they say, 'Oh, actually, it turns out we have to pay you,'" Mark Kelly said. Mark Kelly said he initially planned to provide these samples and perform the related tests for free, to help NASA and the mission. The elder twin served as a sort of experimental control for comparison, offering up biological samples to researchers interested in determining how Scott's long-duration space stay affected his genome, if at all.

![]() ![]() If the device starts to beep to warn you the battery is low during the last hour of use, it’s likely going to wake you. ![]() Such things might disturb you during the night. They should be free of distracting beeps or bright lights.Though not everyone listens to audio all night, folks using headphones to block out disturbances or light sleepers who are using music or white noise to avoid being startled awake will need a full night’s worth of battery power. The National Sleep Foundation recommends seven to nine hours each night, so we added an hour of listening time to allow for winding down before sleep. The battery life should be at least 10 hours.If the speakers and other electronics are challenging to remove and replace, or if the headband doesn’t wash well, you won’t be able to keep your sleep headphones in good condition. But for a fabric headband, you need to be able to wash it regularly. Earbuds require only an occasional wipe-down and sound-tube clearing. They should be reasonably easy to clean.Whether your jam is music, audiobooks, white noise, meditation, or ASMR (video), sleep headphones should let you access what you require. What’s relaxing to one person may be grating to another. They should let you control what you listen to as you fall asleep.If your aim is to block noise, the earbuds must fit properly to seal off your ear canals. If a headband is too tight, it can cause headaches. They should fit a wide variety of head and ear sizes or offer a few sizes to choose from.We also kept an eye out for options that fit the needs of those who wear bonnets or headgear at night. Comfort also means no wires, as it’s easy to become tangled in a headphone cable when you move in your sleep. Earmuffs are best suited for back-sleepers, headband options are best for folks who dislike the feeling of earbuds or earplugs in their ears, and earbuds generally block more external noise. ![]() Sleep headphones primarily come in three styles: wireless earbuds, earmuffs, and headbands with speaker drivers inside.
![]() Barking can be used as a way to attract attention, and any positive response exhibited by the owners reinforces the behavior. Dogs' close relationship with humans also renders dogs reliant on humans, even for basic needs. For example, kenneled dogs may have increased barking due to a desire to facilitate social behavior. Dogs also densely populate urban areas, allowing for more opportunities for socialization. Intruders may frequent the boundaries of a captive dog's territory, thus triggering the bark response as a warning. From a young age, humans may be among a dog's primary social contacts, an environment which presents different stimuli than would be found by wolves in the wild. The frequency of barking in dogs compared to wolves could also be the product of the different social environments of dogs. The behavior of adult dogs also shows puppy-like characteristics: dogs act submissive, whine, and bark often. ![]() Domesticated breeds show vast physical differences from their wild counterparts, an evolution that suggests neoteny, or the retention of juvenile characteristics in adults. Domestication can alter a species and affect their physical and physiological characteristics. Ī hypothesis for why dogs bark more than wolves is that dogs developed vocal communication as a result of their domestication. While wolf barks tend to be brief and isolated, dog barking is often repetitive. ![]() In contrast, dogs bark in many social situations, with acoustic communication in dogs being described as hypertrophic. Wolf barks represent 2.4% of all wolf vocalizations, in warning, defense, and protest. Barking in dogs ĭog barking is distinct from wolf barking. ![]() Researchers at the University of Massachusetts Amherst and Hampshire College have defined a bark as a short, abrupt vocalization that is relatively loud and high-pitched, changes in frequency, and often repeats rapidly in succession. While there is no precise, consistent, and functional acoustic definition for barking, researchers may classify barks according to several criteria. The most common onomatopoeia in the English language for this sound is "woof." "Bark" is also a verb that describes the sound of many canids. Other animals that make this noise include, but are not limited to, wolves, coyotes, foxes, seals, and barking owls. Problems playing this file?

This is supplemented by an 8-point keystone adjustment tool, which aids in getting the image to fit on uneven surfaces. This projector employs a lens with minimal geometric distortion, good uniformity, no visible chromatic aberration, and motorized focusing. Plus, there's a 3.5mm composite video input for legacy sources. ![]() There's also a USB jack for local analog audio playback and an Ethernet connection for wired networking. This limitation precludes adding an external subwoofer as an easy way to supplement the built-in sound. The same goes for the optical-digital output to use it, you have to select it and doing so disables the other audio outputs. The Nova has a headphone/audio aux out 3.5mm jack, but you have to choose between it or the built-in speakers you can't run them concurrently. This UST has three HDMI 2.0 inputs and supports HDR10 source material like UHD Blu-rays, 4K HDR video games, and UHD streaming devices like my Apple TV 4K and Chromecast Ultra. And while the Nova's color saturation is somewhat muted compared to a RGB triple-laser UST, it compensates with its high contrast and color accuracy. Wemax only explicitly claims that the Nova achieves 100% of Rec.709, which is all you need to fully and properly play SDR material. This type of laser light source is cost-effective and avoids the laser speckle of the RGB laser models, but it typically offers a more limited color gamut. The ALPD 3.0 light engine is a blue laser/phosphor wheel design rated to last 25,000 hours. These are standard specs for a midrange 4K UST projector. It uses Texas Instrument's 0.47-inch 1080p DMD with fast XPR pixel-shifting to achieve 4K resolution, while the lens has a 0.23:1 throw ratio. The Nova is a 4K DLP ultra-short-throw projector with a 2,100 ANSI lumen rating. But as you'll read, limitations and issues with its handling of HDR content keep me from recommending it. ![]() It can also output a more than acceptable picture when running in its brightest settings. That gives the Nova a leg up in image quality over some competing USTs, at least when the lights are out and we're talking about SDR content.īudget-conscious AV enthusiasts will find the Nova offers a highly watchable, surprisingly accurate Movie mode right out of the box. The high contrast directly translates to a deeper black level than I'm used to seeing from a DLP projector. The projector achieves a 3,000:1 native contrast ratio, which is quite good for a consumer DLP projector. The brand is owned by Appotronics, which makes the ALPD 3.0 light source used in the Nova as well as the laser light engines for many competitors. The Wemax Nova is a compact and comparatively affordable 4K UST projector. You can read more about the lawsuit here. However, it has a few issues, most notably its poor handling of HDR.Įditor's Note: As of mid-July 2023, the brightness specification of the Wemax Nova projector was downgraded from 2,100 ANSI lumens to 1,300 ANSI lumens following an Epson legal action accusing Wemax of deceptive advertising practices. The Wemax Nova is a $2,699 4K UST with relatively high native contrast and accurate, top-notch SDR color right out of the box. ![]() |
