Joe Tegtmeyer has close up analysis of the Tesla. The Tesla Cybertruck can complete the interior other than the A,B and C pillars along with the front windshield. It is then just five major parts to complete the outside body including the bed of the cybertruck. This is far fewer parts and steps for the …
Rolls-Royce has successfully run its UltraFan® technology demonstrator to maximum power at its facility in Derby, UK. The initial stage of the test was conducted using 100% Sustainable Aviation Fuel (SAF). This will make improved efficiency for current and future airplane engines. This is an important milestone for the UltraFan demonstrator, which was successfully tested …
Elon Musk says the next-generation Raptor engine that is robust enough not to require a heat shield. It will also have more thrust, higher Isp and many other improvements. Could make them faster, but engine production is not the limiting factor. I’m very excited about the next-gen Raptor engine that is robust enough not to …
The US companies with mainly French and British Partners dominate the market share of the global aircraft engine market: CFM International: 39% Pratt & Whitney: 35% GE Aviation: 14% Rolls-Royce: 12% This commercial aircraft engine domination supports the US domination of military jets. The high tech alloys and advanced enables the military jet engines to …
The F-35As have critical failures every 11 flight hours and airframe-only (excluding engines and systems) maintenance is 4.4 man-hours per flight hour. The US air force is trying to fly its F35s from 250-316 hours each year. This would mean 1100-1400 hours each year on airframe maintenance and more hours on engines and systems. Each …
There have been reports that South Korean researchers have made a practical regular atmospheric pressure room temperature superconductor using basic lab equipment. This would mean superconducting wires and magnets that would not need special cooling. Depending upon your application you might still want to cool the system but you could use regular refrigerants. NOTE: The …
DARPA is trying to use new more powerful superconducting magnets to triple the efficiency of a Magnetohydrodynamic drive for ultra-quiet navy ships. The PUMP program will develop an electrode material system solution for an efficient and reliable magnetohydrodynamic drive. The program will have multiple components to achieve this goal, including a modeling and simulation design …
SpaceX Raptor 3 is an improved and more powerful rocket enigine. It has reached 350 bar of pressure and 269 tons of thrust. Raptor 2 engines were achieving 230 tf (510,000 lbf) of thrust consistently by February 2022, although SpaceX expects to be able to tune engine parameters and design over time to achieve at …
Elon Musk recently tweeted out on December 2nd and mentioned that the current efficiency of the Tesla semi is 1.7 kWh per mile. He also mentioned that there is a clear path to 1.6 and possibly 1.5 kWh per mile. One gallon of gas is equal to around 33.7 kilowatt hours of electricity. This means …
Ingineerix tears down Tesla’s newest Hairpin Motor and Inverter technology. It is the fourth generation engine. It has more power than the old winding motors and is easier to build with automation. It is the rear drive unit for the Model Y and Model 3. They have a new hairpin design stator. Everything about the …
The Blue Origin BE-4 might get certified for flight tests by December of this year. It is about 5-6 years late for an original 2017 planned operational date. The BE-4 engine project started in 2014. It would be the most powerful liquefied natural gas (LNG) fueled rocket engine ever developed. Using an oxygen-rich staged combustion …
