The main problem holding back reusable hypersonic planes is that traditional ramjet engines become very inefficient over mach 2 while hypersonic engines do not work well below mach 4. There is the need to solve the hypersonic speed gap between mach 2 and mach 4. Rotating Detonating Engines can be more efficient up to mach …
The SpaceX Starship fleet is now over four Starship and three Super Heavy Boosters. The construction of over one Raptor engine per day in 2024 will enable ten Starships and Super Heavy Boosters to be built in 2024. The Raptor engine factory has the capacity to make over eleven Raptor Engines per day. This would …
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 …
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 …
There are reports that a third batch of China’s WS-15 turbofans has been delivered with performance better than US F135. This would mean that China has achieved the goal of about 197 kilonewtons (44,000 lbf) of thrust with an afterburner.
Agile Propulsion engines are well suited for lunar and planetary landers and upper stages. The lower temperature propellant would be good for sample return from the moon. #SpaceAccess2019
Reaction Engines is working towards air-breathing space planes and hypersonic airplanes. They have successfully tested their critical pre-cooler technology at the temperature conditions it would experience at 3.3 times the speed of sound. The pre-cooler quickly drops the temperature of the air so that the engines for a space plane or hypersonic vehicle would not …
Spadre.com is reporting that SpaceX is performing the first new raptor engine firing on the Spacehopper. The Spacehopper is being held down with tethers. Every Day Astronaut is also reporting live on the test firing. Sheriff just advised road closure will begin at 9:30am. (UTC – 5) livestream https://t.co/ENYz4e0tWI will remain until road closure at …
Researchers have used an ensemble of NV− centers in diamond for implementing different types of quantum heat engines. They have used these to demonstrate the equivalence of the power output of two different engine types, continuous and two-stroke, for small actions. Additionally, they have shown that, for very small actions, the engines produce more power …
