How to make a Tesla Valve for a "Pulse Jet Engine" - YouTube The event will happen immediately after its annual shareholder meeting on September 22 at 1:30 p.m. Pacific time. Marin-Martinod suggested that the batteries could arrive in the next few years, and the electric airliner could hit the skies in 2040. I favor the image of the jam jar design because it came up in a story I read or imagined about a polar army base and the rhythm of the pulse jet heaters made from barrels of kerosene with holes punched out of the lids. He is the cofounder of Tesla Motors and Space X. Musk net worth is US$ 11.4 billion. Korus shared a post that showed battery-technology firm Amprius is located near Tesla's facilities in Fremont. Too noisy and not the pressure levels I wanted. My current jet engine work does not include a Tesla Valve, though much of it is inspired by it. The components in the front are not that different from a typical jet engine, except the output of the compressor turbine scroll is where fuel may be injected, as to better atomize, emulsify and vaporize the fuel, although direct injection into the pulse jet chambers may be safer. The two things that come to mind for me are theTesla valveand thevalveless pulse jet. The design seems complex, but I've done my best to simplify it without an engineering degree. Today I just wanted to talk about things with no moving parts in some sense. This battery would also need to be produced in volume, rather than just an experiment in a lab. As it rotates, it allows some jets to fire and creates low-pressure conditions for exhaust particles to ignite the new fuel-air mixture. The main obstacle is battery density, or how much energy each kilogram of battery can hold. In a 2016 interview, Musk said the jet would take off and land vertically. Sorry if some details aren't clear. Tesla valvular conduits prevent air from backing up and creating resistance in the compressor turbine. Electrek noted Monday that the main event motif bears resemblance to silicon nanowires, an exotic battery technology that could electrify aviation. This pushes the compressed air around the transmission enclosure, which can cool the transmission units. Contest Notifications:Click here for the full list of 2019 winning entries. Variation comes from friction with the planet carrier (reduction) or power input to the carrier and sun gear (slight overdrive). A typical jet engine exhaust turbine can't handle pulses all that easily, so the exhaust scroll of choice is the Tesla turbine, a centrifugal turbine consisting of a series of perforated discs mounted on a drive shaft, powered by tangentially shooting air in between the discs. Illustration of selfmade Pulse Jet with experimental valve head. But the idea is IMHO really promising. A pulsejet engine (or pulse jet) is a type of jet engine in which combustion occurs in pulses.A pulsejet engine can be made with few or no moving parts, and is capable of running statically (i.e. For now, Tesla seems more focused on its energy and car businesses than aviation. It's the initial takeoff phase that's tricky, and that's where density is key. (LogOut/ In 2008 Musk noted that an electric plane gets more feasible as battery energy improves, and four years later he said he had a design in mind for years. Tank you! (LogOut/ Musk even mentioned the idea during his cameo in the 2010 film Iron Man 2. I eventually moved away from pulsed combustion though. But if battery technology improves and it becomes feasible to electrify a jet, it could enable humanity to transition to a fully zero-emissions transport system. Finally, it may become reality. He also owns a Dassault Falcon 900 B with registration N900SX. Change), You are commenting using your Facebook account. The rotary disc valve is not directly connected to the transmission- there is an intermediate planetary gear initially set to a 1:1 ratio with the planet carrier and planetary gears 'locked'. This allows for improved timing in different conditions. This is not at all like having actual valves that close that the gases can bounce off of, or like in a valvless pulse jet where the pipe is as short, and bent back so you can harness some of the energy the exhaust; However I am a big fan of Tesla and you need to look at it in the proper context. Musk claimed in his Twitter post that this breakthrough is "probably 3 to 4 years" from reality. When I began, I imagined using a pulse jet, and attaching an axialy rotated tesla valve to the front of it, in order to replace the reed valves. Elon Musk is the owner of a Gulfstream G650 private jet with registration N628TS. Fill in your details below or click an icon to log in: You are commenting using your WordPress.com account. So where is it? For the electric jet, though, increases in battery density could make the vehicle dramatically more useful. The news comes as Tesla announced plans for its upcoming Battery Day. Tesla electric jet: Elon Musk says a key technology is 3 to 4 years away. Sam Korus, an analyst at ARK Invest, wrote on Twitter that removing 150 kg (330 pounds) from a Tesla Model 3 would add just 15 miles to the car's range between battery charges. Tesla CEO Elon Musk has spoken before about his dream to build an electric jet. It's unclear what Tesla will announce at its battery event, but it could be the first steps on the path to an exciting new future. Amprius claims to be able to reach past that 400 watt-hours per kilogram mark, with its 100 percent silicon nanowire batteries the same technology speculated to be the backdrop for Tesla's Battery Day webpage. Finally, it may become reality. Change), You are commenting using your Twitter account. Estimates are that Tesla turbines are roughly 55-60% efficient under load, but have an inherent low torque output since they are bladeless. When I find a forgotten concept with merit, or learn of some new and exotic mechanism, I challenge myself to find a way to apply it. Doesn't really interest me if it's true or not. Perhaps proper engineering makes such considerations unnecessary or the geometry of a valveless pulse jet makes it ade factoTesla valve. Thierry Marin-Martinod, aerospace and defense chief technology officer for TE Connectivity, told Inverse in July 2019 that the battery would be the first hurdle, before working out issues with voltage and regulations. To compensate for low torque, the turbine's output is attached to a 2-stage planetary gear transmission, featuring coaxial outputs. Battery Day could be a step toward that reality. There is also a low-resistance alternator inside in case the pulse jets need the assistance of some spark plugs or in case any platforms using this engine need a supply of electricity. Current electric car batteries are around 250 watt-hours per kilogram, Musk claimed in 2018. Responding to a Twitter thread about the potential for an electric jet, Musk stated that the futuristic zero-emissions jet would require a battery pack with a density of 400 watt-hours per kilogram. The Inverse analysis Electrifying ground-based transport is arguably more important than electric jets. Click here for the full list of 2019 winning entries. Thanks to "kasraoui" for the spark plug! That's important for flight, as a plane needs to overcome the force of gravity to lift off in the first place. A typical jet engine exhaust turbine can't handle pulses all that easily, so the exhaust scroll of choice is the Tesla turbine, a centrifugal turbine consisting of a series of perforated discs mounted on a drive shaft, powered by tangentially shooting air in between the discs. His jet is a G650ER with extended range. Musk said in a 2018 interview that the electric jet "isnt necessary right now" compared to electric cars. The first planetary gear set drives a rotating disc valve and the compressor scroll. The outputs from the planetary gears then drive the sun gear of the second gear set, which drives the turbofan at the front, which is optional and may be absent for some variants of the engine. The two things that come to mind for me are the Tesla valve and the valveless pulse jet.. Tesla CEO Elon Musk has spoken before about his dream to build an electric jet. (LogOut/ Musk explained in September 2018 that the energy used for cruise speed is actually quite low, and the plane can depend on gravitational potential energy for the landing phase, so it doesn't need a big bank of reserve energy to return. The pulse jet aspect improves combustion efficiency by doing combustion in pulses, reducing fuel consumption over time. (LogOut/ I can't create a prototype, it's impossible for me to get one made off alu or steel :( If you can try this thing please send me a message. Today I just wanted to talk about things with no moving parts in some sense. Their forte is high efficiency at high RPM, and they can handle pulse detonation. That's how it's been, that's how it's going to keep on being. The World Resources Institute found that while transport emissions accounted for 24 percent of the world's carbon dioxide emissions in 2016, road-based transport accounted for 72 percent of those emissions. The pulse jets are controlled via the rotary disc valve, which is another disc with perforations, this time out towards the periphery (Tesla turbine discs are perforated towards the center) and are inline with the inlets to the pulse jets. The top-of-the-head thought is that, while the valveless pulse jet really does have a non-moving valve, Ive never seen a pulse jet with a Tesla valve. The Tesla Turbopulsejet is a (hypothetically) low cost, highly efficient and compact jet engine, using patents and inventions from 20th century inventor Nikola Tesla, as well as the use of pulse jet engines. Change), You are commenting using your Google account. Change). A key technology that could enable an electric jet may be just three or four years away, Tesla CEO Elon Musk claimed Monday and Tesla could be set to reveal some more advancements in the space soon. Let's just neglect, the story behind it. The pulse jet aspect improves combustion efficiency by doing combustion in pulses, reducing fuel consumption over time.
