The Chinese military is once again pushing the boundaries of technological innovation by incorporating bird-shaped reconnaissance drones. Recent images circulated on the Internet show these drones in use by one of the units of the Marine Corps of the People’s Liberation Army (PLA).

These drones, indistinguishable from living birds at a distance, flap their wings and fly in a natural manner. Technical details and specific characteristics of these drones remain confidential, but their deployment within the PLA forces has been confirmed.

China is not new to the field of ornithopters. As early as 2018, a government program named “Pigeon” was launched, aimed at developing mimetic drones for urban operations. These drones, with their characteristics still undisclosed, were designed to blend into the urban environment without arousing suspicion.

In 2022, Chinese engineers unveiled an impressive mechanical flying bird weighing 1,600 grams and featuring a wingspan of two meters. Powered by a lithium battery, this drone could remain airborne for an hour and a half, demonstrating China’s advancements in the field of biomimetic drones.

Although many countries are also working on bird-like drones, most are limited to fixed-wing models propelled by propellers. For instance, the Dutch surveillance drone Evolution Eagle, disguised as a large eagle, can only deceive the human eye from a great distance. In contrast, the Chinese flapping-wing drones offer a much more effective and realistic camouflage.

This technological advancement reflects the Chinese military’s desire to remain at the forefront of military innovation by developing equipment capable of perfectly blending into their environment for discreet and effective reconnaissance missions.

The adoption of these ornithopter drones by the PLA could mark a turning point in surveillance and military intelligence strategies, offering a significant tactical advantage due to their ability to operate without raising suspicion. It remains to be seen how this technology will be exploited in the coming years and what impact it will have on military doctrines worldwide.

#Constellation #Aquila

Look halfway up the southeastern sky in early August evenings, and you’ll easily spot the bright, white star Altair, sitting at the bottom corner of the Summer Triangle asterism. Altair is the brightest star in the venerable constellation of Aquila (the #Eagle) and marks the great bird’s head. The eagle’s body and tail extend downwards to the right, more or less following the Milky Way. The #wings extend upwards and downwards.

Altair is Arabic for “flying eagle”. The star itself is a yellow-white star about ten times larger than our Sun, and only a mere 17 light-years away, making it the twelfth brightest star in the night sky. At 10 hours, its rotation rate is one of the fastest known, spinning so rapidly that the star has an oblate shape (wider at the equator than it is tall). In the sky, Altair is symmetrically flanked by two small stars named Alshain and Tarazed. The trio span about three finger widths, or 5° of separation. Tarazed is a cool, orange giant star located 460 light-years away and shining at almost 3,000 times the luminosity of our Sun.

The rest of Aquila’s stars are dimmer, but nonetheless visible to unaided eyes. Almost a fist’s diameter to the lower right of Altair is the star Delta Aquilae, representing the body. The upper wing has the star Okab at the tip. The lower wing is formed by two widely spaced stars named Almizan I and Almizan II. The eagle’s tail is marked by a pair of small stars named Al Thalimain, “the two ostriches”.

In Greek mythology, the constellation had been associated with Aetos Dios – the eagle that carried the thunderbolts of the supreme god, Zeus. The eagle was also sent by Zeus to carry the shepherd boy Ganymede to Mount Olympus. Ganymede is often associated with the constellation of Aquarius.
