Turbo Ramjet Engine, Mach 3+ - Jet Engine (Only)

myminifactory

In order to fly from the ground to supersonic speeds of Mach 3+, the combination of Turbojet Engine and Ramjet Engine is required, and this is called Turbo-Ramjet Engine.The only operational aircraft to achieve this goal was the Lockheed SR-71 Blackbird supersonic, high-altitude strategic reconnaissance aircraft, which first flew in 1964 and remained in service until 1989.This extensive flight was achieved using the Variable Bypass Afterburner Jet Engine (P&W J58 (JT11)) in conjunction with Special Inlet Propulsion System, setting the jet aircraft speed record of 3,530 km/h (25,929 m altitude) in 1976. .It is a famous aircraft, and a lot of information is published on the Internet and in books, and many plastic models are sold.This time, I challenged to make the educational model that will make it easier to understand the basic configuration and functions of spikes, valves, nozzles, doors, etc. that operate at various speeds. A. The contents of each component are as follows.(1) Inlet Propulsion System (Nacelle)(Model Size: 128Diax850～900mmL)　　① Spike　　② Center Body Bleed　　③ Shock Trap Bleed　　④ FWD Bypass Door　　⑤ AFT Bypass Door　　⑥ Suck-In Doors　　⑦ Tertiary Doors　　⑧ Ejector Flaps　　[High temperature measures] Extensive use of titanium(2) Jet Engine - Variable Bypass, Continuous use afterburner (Model Size:110Diax200mmL)　　　 Single Shaft Turbojet Engine　　　 Compressor-9stages, Turbine- 2stages, Can (x8) annular Combustor　　⑨ Variable Inlet Guide Vane (trailing Edge ) (Dummy)　　⑩ Bleed (Bypass) Valve and Ducts (x6) from 4th Stage　　⑪ Afterburner Spray Ring and Flame Holder　　⑫ Variable Exhaust Nozzle　　⑬ Direct Drive from External Starter　　　　[[High temperature measures] use of titanium, Heat resistant Alloy　　　　　　　　High flash point fuel (JP-7)、Chemical ignition (TEB: Triethylborane)　　　　　　　　High-temperature lubricant (Silicon-based grease) [Video] youtu.be/da520YYTyAA B. Assembly Manual (PDF format)　The manual is structured as follows　(1) Inlet Propulsion System (Nacelle) (TJE-07INLET) (25 pages)　(2) Jet Engine - Variable Bypass, Continuous use afterburner (TJE-07) (22 pages)　The detail assembly manual including "Parts-List", "After printing treatment" and "Assembly procedure" are prepared based on "Standard Skill (Filing, Drilling, Tapping and painting)". C. Purchase Parts Information;　-No Metal Bearing　-Aluminum Pipe : φ3, 7 (ENG) and φ10 (INLET only)　　　　　-ABS Pipe : φ5　-Piano Wire : φ1　-Screws M1.4 and M2 - Size can be changed by your experience. D. STL file　　STL files of this model are 57 items (TJE-07) and 53 items (TJE-07INLET).　　"ws" of last 2 digits of file name means "With Support" special designed. E. Total Net Print Time: Approx. 93 HR (TJE-07) and 171 HR (TJE-07INLET)　- (Estimated as case of PLA, 0.4mm Nozzle, 0.2mm Layer Height, 40% infill and No raft and support)　　Note: When at actual print, each parameter may be adjusted by your experience.　　　　　All parts can be printed using with 130(W)x150(L)x100(H)mm Printer. Before "Down-Loading", please watch photos carefully and consider deeply.I wish you success!!.
