First macro-observation: the GCAP requirements are different from anything else. Much bigger for a start. Think F-111! The last generation of European fighters were essentially F-16 or F/A-18-type fighters with added capabilities. South Korean and Turkish designs today, and the Shenyang FC-31, are US-inspired. Not so GCAP, formed to a Euro-Japanese requirement that edges towards the light-bomber end of the fighter spectrum, with an emphasis on payload and range, in a way we have not seen since the 1960s. The wing’s shape and size contribute to performance in two ways: massive fuel volume and low drag in cruising flight. Both promote range. It’s not a classic delta in the style of the Mirage III’s; it’s more like the capacious wing of the promising but never built F-16U, from 1995, or that of the Boeing X-32 contender for the Joint Strike Fighter program. The F-16U carried 80 percent more internal fuel than the standard aircraft; the X-32 wing, only half the area of the GCAP wing, could accommodate 9 tonnes of fuel, compared with 3.2 tonnes in the F-16C, for example. The GCAP should have a usefully greater combat radius on internal fuel than most other current combat aircraft can manage with external tanks, while leaving space in the lower fuselage for weapons. That makes a lot of sense for a stealth aircraft, where fuel and bulky weapons must be carried internally. Among the tactical opportunities of greater range is use of bases farther from the territory of the opponent–say, China. They would be more costly to attack with missiles and easier to defend. The large span and area of the GCAP’s wing contribute to efficiency in cruising flight and good turn performance. The relative size of the engine inlets and exhausts and the smallness of the vertical stabilisers suggest that, to dominate the fight, the designers are not going for ultimate agility but are relying on sensors, long-range weapons and even teaming the fighter with uncrewed aircraft. (An aircraft this size could carry uncrewed vehicles into the fight under its wings, releasing them outside detection range.) One wonders whether the European and Japanese planners have read the air combat study by researcher and former US Air Force pilot John Stillion, which pointed to a trend to longer-range engagements.

MIT STUDY: REDUCING CAR SPEED TO 20MPH / 30KMH INCREASES ALL POLLUTION: 'According to a MIT study in Milan, the 30 km / h limit causes more pollution' 'The heat engines are designed to have the best efficiency around 70-80 km / h and travel times are also longer' "The reduction of speed limit at 30 km / h - a measure that aims to make cities more livable, safe and less noisy - causes not only a slight increase in travel times but it also has polluting emissions. This is what one detects study of the MIT Senseable City Lab, of the famous Massachusetts Institute of Technology in Boston, focused on the city of Milan and presented on the occasion of third forum of The urban mobility council, the mobility think tank promoted by the Unipol Group.  The speed reduction to 30 km / h determines a increase in carbon monoxide emissions (CO), carbon dioxide (CO2), nitrogen oxides (NOx) e particulate (PM), especially in the busiest hours of the day, because, explains the study, thermal engines are designed to have the best consumption efficiency around 70-80 km / h. In case of application of the 30km / h limit in the entire territory of the Municipality of Milan, CO2 emissions would increase by 1.5%, while those of PM, particularly harmful to human health, 2.7%. https://lnkd.in/dxxQkvZP

#Electric propulsion enters #defence – observed at ILA Berlin - Pioneering Aerospace 2024     Have #eVTOL aircraft lost their innocence? This is a glimpse of recent developments, in which electric propulsion is used for military purposes.     1. Deadly #quadcopters   You guessed it, even the average quadcopter can be and will be used as “loitering ammunition”. #Donaustahl’s “Maus” is an example for a low-end, low-cost killer drone. Specifically developed for (and with) Ukraine to counter the Ruzzian aggressor.     2. The electric dual-use #surveillance #UAV   For high-end eVTOL UAVs look no further than Quantum-Systems. Originally developed for civil applications, their family of mid-range UAVs now provides very useful intel in Ukraine. The 1-cruise plus 2-lift motor system with folding props turns out to be the true dominant design for surveillance. As expected.     3. An electrically augmented #multipurpose #UAV   More endurance required? Rheinmetall just equipped its LUNA NG UAV with four e-motors. Only the VTOL capability is electric, but electric it is. Due to weight and drag increase as well as cruise speed drop endurance may drop from 12h to 9-10h – but versatile it is.     4. A multipurpose UAV with electric “mothership”?   Even more endurance? Well, meet Insitu Inc’s Integrator UAV combined with FLARES (Flying Launch and Recovery System) an eVTOL UAV developed by #HoodTec. It’s as crazy as it looks – a giant “spider” (their wording) lifts and accelerates Integrator and returns. Only to dash off again and to “lasso” Integrator back in (yes, by recovery rope!) on return. US Wild West? Maybe, but Integrator maintains its long endurance and range, while FLARES stays local.     5. Defence against #drone #swarms?   Since 2014 I have been deeply concerned about the “dark side” of drones. Consequently, already in February 2015 I launched a students’ project on methods for defending soft targets against drone swarm attacks.   The “Maus”, applied in swarms of 10-30 drones represents exactly what I have been worried about. Such swarms operated by terrorists are a nightmare.   That’s why I suggested a new use case for Insta Defence & Aviation’s Steel Eagle™ (quadcopter based). There’s a configuration change required, but the defence capability is promising. Please contact me if you are interested in this – including if you are good in swarm flying (ping Stephen Sutton).     In summary – with all the military applications – at least multi-copters indeed lost their innocence. However, especially in the US, that means money, with almost ubiquitous military-based funding. Europe is slowly catching up, and as long as the results support Ukraine and the fight against terrorists, I am in. Some dominant designs have emerged, and also pretty wild stuff. My focus – besides my own eVTOL aircraft – is on swarm defence.     => For more info on defence check Luca Leone; for counterintelligence and security R.S. V. and for dual use Florian Seibel.

China's SIGINT/ELINT signals intelligence satellites: China has about 10 Tongxin Jishu Shiyan (communication technology test) satellites in geostationary orbit, some of which are stated to be SIGINT satellites with a large dish antenna. These are located above the western Pacific and Indian Oceans. China also has Yaogan ELINT satellites which operate in clusters of three satellites in LEO orbit (low earth orbit) which can carry out coordinated radio signals time difference of arrival (TDA) for detection and localization of emitting transmitters. These are likely Yaogan 9A-9B-9C, 16A-16B-16C, 17A-17B-17C, 20A-20B-20C, 25A-25B-25C, 30-1A-1B-1C, 30-2A-2B-2C, 30-3A-3B-3C, 30-4A-4B-4C, 30-5A-5B-5C, 30-6A-6B-6C, 30-7A-7B-7C, 30-8A-8B-8C, 30- 9A-9B-9C, 30-10A-10B-10C, 31A-31B-31C, 31D-31E-31F, 31G-31H-31J, 31K-31L-31M, 35A-35B-35C, 35-02A-02B- 02C, 35-03A-03B-03C, 35-04A-04B-04C, 35-05A-05B-05C, 36A-36B-36C, 36-02A-02B-02C, 36-03A-03B-03C, 36- 04A-04B-04C, 36-05A-05B-05C, 39-01A-01B-01C, 39-02A-02B-02C, 39-03A-03B-03C, 39-04A-04B-04C and 39-05A- 05B-05C, i.e. 34 groups with a total of 102 ELINT satellites. The ELINT satellites are probably primarily designed for naval surveillance and are similar to the United States' Naval Ocean Surveillance System (NOSS), but of course can also be used for detecting and locating emitting transmitters on land. Yaogan ELINT satellites began to be launched in 2010. Since 2020, 24 of the 34 groups have been launched. China does not have a developed geostationary SIGINT/ELINT capacity in the same way as the US with the MENTOR satellites. But China's NOSS capacity is greater as compensation compared to the US NOSS third generation. The US NOSS third generation consists of pair-operating ELINT satellites (compared to the previous three) which can probably cooperate with MENTOR for detection and localization of emitting transmitters.
