The prototype of the Russian passenger airliner Superjet 100 with PD-8 engines reached a maximum flight altitude of 11,300 meters and a flight speed of 955 km/h. During the test flight, the pilots showed the instrument panel of the Sukhoi Superjet 100. The plane was in the air for 3 hours and 13 minutes. During the flight, the gas-dynamic stability of the engines was checked at altitudes of 3,000, 7,600, 9,000 and 11,300 meters. The Sukhoi Superjet 100 airliner can carry from 87 to 108 passengers over a range of 3,050 or 4,600 km. The approximate price of the Sukhoi Superjet 100 is from 39 to 50 million dollars, depending on the configuration.

The Russian experimental medium-haul aircraft MS-21-310 with the PD-14 engine and import-substituted components made its first flight over Irkutsk. PD-14 is the first new-generation aircraft turbofan engine created in modern Russia. The operation of the PD-14 engine is shown in the link to the video in the comments to the video. The passenger aircraft MS-21 took off from the airfield of the Irkutsk Aviation Plant. The flight lasted 1 hour 15 minutes, the airliner climbed to an altitude of 3,000 meters and developed a speed of 580 km / h. Two modified experimental aircraft MS-21 are taking part in flight tests under the import substitution program. The MS-21 aircraft is a Russian medium-haul airliner developed by the Yakovlev Corporation to compete with the Boeing 737 and Airbus A320 aircraft. Russian analogues have not replaced all foreign systems of the aircraft. The airliner received a Russian onboard electronics complex, including switches, computers, navigation systems, an auxiliary power unit, pressure and air conditioning control devices, lighting devices, and aircraft system consoles. Russian components were also included in the power supply equipment, hydraulic systems, and chassis. The MS-21-310 aircraft can carry from 163 to 211 passengers at a speed of up to 870 km/h. The flight range is about 5,100 km, and can be increased. Serial production of the MS-21 is planned to begin in 2026.

Scientists are closer than ever to developing a universal antivenom for snake bites after analysing the blood of a man who was bitten more than 200 times – on purpose.

For almost two decades, Tim Friede, a self-taught herpetologist, has been exposing himself to venom from more than a dozen of the world’s most dangerous snakes, in a highly unconventional attempt to build up some protection against the reptiles.

Now, researchers say they have used antibodies extracted from Friede’s blood as the foundation for an antivenom cocktail that offers complete or partial protection against 19 dangerous snakes – including king cobras, black mambas and tiger snakes.

“When I met this guy, who spent 18 years injecting himself with all manner of snakes from around the world, I thought he may have the secrets for a universal antivenom pumping through his veins,” said Dr Jacob Glanville, chief executive of Centivax, a biotechnology company.

Just one more decade and you will have 17 or so.

Only one a/c has a Russian carbon fibre wing and the exchange of the Collins FBW isn't even mentioned as it didn't happen bc Russia has no substitute also few other systems didn't get substituted.

That what was Russified added 5.75 t and insiders say it has now only a range of 2000km and a service ceiling of 7000m.

For comparison Airbus needed only 10 years from idea to serial production including a complete redesign in 2006 for the A350.

And built 651 in eleven years.
