Leviathan

Hello everyone, I'm pleased to present a new version of my RISE motor: it differs from the previous one in that it doesn't have a power up motor on the support foot. With this version, I wanted to operate the internal mechanics via the extraction cone at the rear of the motor. This makes it easier to vary the speed of rotation of the various compressors while playing with the variation in incidence of the blades. The inventory has been simplified and some minor design and assembly corrections have been made, such as reversing the angle of the low-pressure turbine at the rear of the engine (convergent to divergent). I hope you will like this new version, the building instructions are available on Rebrickable : https://rebrickable.com/mocs/MOC-198495/Levihathan/cfm-rise-engine-manual-version/#details You can also support the project on LEGO IDEAS : https://ideas.lego.com/projects/077efa86-88a4-43d0-930f-c6486d529361 See you !

Hello, I've reached the 200 votes on Lego Ideas ! For this occasion and because I like this kind of stuff, I've made an BluePrint for the RISE engine : You always can support the project here : https://ideas.lego.com/projects/077efa86-88a4-43d0-930f-c6486d529361

Thank you !

Hello guys ! I'm trying Lego Ideas adventure ! If you want to support this project, you can make it following this link : https://ideas.lego.com/s/p:077efa8688a443d0930fc6486d529361 Thank you in advance !

Hello, I have made a animated gif to understand the mechanism : To put it simply: the turquoise carriage is moved backwards by the white rods. As it moves backwards, the carriage tilts the green and coral blades, which are mounted on an cam. Finally, the green parts rotate, linked by a 12/20t angle gear. The entire mechanism is returned to its initial position by 2 springs (not shown).

Thanks for your comment, I hope you'll enjoy building according to the instructions! That's the whole point of a demonstrator: to be disruptive! Beyond the design, the fuels with which the engine is compatible also give hope. Yes! you can find it here : https://rebrickable.com/mocs/MOC-133571/Levihathan/cfm-leap-engine/#details Regards !

Thank you very much !

Thank for your comments guys ! Glad to hear you enjoyed the model !

Hello everyone, I'm pleased to present my latest personal creation: the CFM Group's RISE engine! This is a turboprop engine program known as Open Fan, i.e. without a nacelle enclosing the main fan. This kind of prototype, still at the demonstrator stage, should equip future aircraft by 2025-2030, if promises of reduced fuel consumption are kept! (https://www.cfmaeroengines.com/wp-content/uploads/2021/07/CFM_RISE_Whitepaper_Media.pdf) Like my version of the LEAP 1C already built in 2021 (https://www.flickr.com/photos/147164115@N07/albums/72157718957968196/with/51653430599/), I wanted to propose a standing model version once again with functional and motorized elements. I started the design at the end of 2023 and spread it out over 7 months. The final model is made up of around 1,300 parts, measuring around 20cm in diameter and 30cm in length. The big technical challenge lay in the mechanism for varying the incidence of the main rotating and fixed blades in a single movement, using a lever concealed in the base of the support! Let's see the photos: Technically speaking, to fully understand the concept, we need to distinguish between the "rotating" front fan blades and the "fixed" rear blades. A central mobile made up of 2 cradles is guided in translation by a linkage system. In transit, this mobile tilts all the eccentrically-mounted blades. The trick thing about this mechanism is that, from a single translation movement of the mobile, the front blades turn anti-clockwise, while the rear ones turn clockwise. You'll see, it's easier to understand on video! Of course, the entire mechanism operates when the motor is rotating. In addition to the technical challenge of packing this mechanism into a small footprint, I didn't neglect the aesthetic aspect of the motor to make it recognizable. Some will notice the painted parts on the blades and the nose. For the cylindrical part, which is always tricky to render in Lego, the motor is made up of 1 10-sided barrel using this assembly technique: https: //brick.camp/en/tech/clip-handle-swivel-decagon. In the compressor section, the rotating skirt is also inverted to fit under the conical cowling. Thank you for your reading, I hope you enjoyed it !

Hi guys, here my Bilstein version from 24 heures of Nürburgring ! I used some Webrick brick for blue panels :) Thank you @DugaldIC for this creation !

Hello everyone and happy new year 2022 ! Building instructions are now available on Rebrickable : https://rebrickable.com/mocs/MOC-96897/Levihathan/poclain-hc300/#details I've achieved the book with subassemblies sequence : See you soon !

Thank you ! Yes, designers understood how to mix up sport car and Neo-retro style. I read this article (in French) to learn more about the car details : https://www.automotivpress.fr/essai-jannarelly-design-1-une-emotion-francaise/

Yes I created a custom profile in PU app but I don't know how to share it ! Into the app you can mix any kind of hub you want. Here you can see controls. As you can see, you can move the excavator at the same time moving the boom for example. Each joystick has in own motor. You can reverse each motor rotation on the app with number one in red circle : -1 or 1.

Thank you !

Thank you ! Here is the video : I hope you will enjoy it !
