DARPA and the Navy had envisioned hyper-efficient cargo planes able to move thousands of tons by leveraging extra lift by flying close to the ground. Regent craft has a working 12 passenger version and has sales for a 100 passenger seaplane that would be about three times more fuel efficient than other planes. They do …
All-electric seaglider manufacturer Regent Craft will deliver its first 50-100-passenger Monarch seaglider to United Marine Egypt (UME) Shipping before the end of the decade. The vessel is an all-electric hydrofoiling wing-in-ground (WIG) craft, which means it always operates in ground effect, an operation that occurs within one wingspan of the surface of the water and …
Here’s a summary of the major problems associated with various Boeing aircraft models and projects, based on the information available up to August 2024: Boeing 737 MAX Crashes: Two fatal crashes (Lion Air Flight 610 in 2018 and Ethiopian Airlines Flight 302 in 2019) led to the grounding of the entire fleet due to issues …
A Boeing 777 lost a wheel taking off from San Francisco and a 737 had a landing gear failure this morning. This is the fourth incident United Airlines has had this week. A 757 suffering an engine failure on descent into SFO and Boeing 737-900 from United at Houston suffering an engine stall. This is …
Three days ago an Alaska Airlines operated Boeing 737 Max 9 lost a door plug as seen in the photo. A three foot by six foot opening was left where the door plug was. The flight was three miles (14850 feet) off the ground so the decompression and other issues were not catastrophic. The pressure …
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 …
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 …
DARPA and Aurora, subsidiary of Boeing, are making a breakthrough X-plane without regular flights controls. The Control of Revolutionary Aircraft with Novel Effectors (CRANE) program aims to design, build, and flight test a novel X-plane that incorporates Active Flow Control (AFC) as a primary design consideration. Crane seeks to optimize the benefits of active flow …
The U.S. Department of Energy (DOE) announced up to $100 million in funding to support clean energy technologies by providing a path to market for promising technologies. Developing and deploying innovative energy technologies is key to delivering a clean energy future and achieve net-zero emissions economy-wide by 2050. Between the 2019 and 2021 cohort, ARPA-E …
China’s PLA’s Eastern Theater Command announced the end of a large military exercise today. Taiwan’s R.O.C. Armed Forces will continue to keep a close watch on PLA’s movements 24/7 and act accordingly. On Monday, China’s Navy had 11 ships and 70 PLA aircraft near Taiwan and about 35 of the planes crossed the median line …
The only working copy of the Antonov An-225 was destroyed in 2022. It could carry 190 tons of payload and had a max takeoff weight of 640 tons. The Lockheed C-5M is largest regularly operating plane. Upgraded C-5s are designated C-5M Super Galaxy. The C-5s were given new General Electric F138-GE-100 (CF6-80C2) engines, pylons and …
