Hmm no 50% by weight means much more than 50% by volume, since it’s large volumes of lighter materials combined with smaller volumes of heavier materials. Pretty sure there will be more aluminum in the internal structural supports.

Aviadvigatel conducted open air testing of the PD-35 engine at a new ground test stand.
After ground testing is done they would have to do captive carry testing with an aircraft. Be it an Il-76 test airplane or similar.

The team of UEC-Aviadvigatel of the United Engine Corporation became the winner of the Aircraft Builder of the Year award in the nomination "For achievements in the development of aviation equipment and components (Design Bureau of the Year)" for the creation of the PD-35 technology demonstrator engine.
For the first time in Russia, an engine with a thrust of 35 tons has been designed and manufactured. It was developed within the framework of the program for the creation of high-thrust aircraft engines and is intended to test key technologies and demonstrate their maturity for use in projects to create advanced engines.
The first stage of testing of the PD-35 technology demonstrator engine was successfully completed at the new open test facility of UEC-Aviadvigatel, specially created for testing engines with a thrust of 24 to 50 tons.
During the tests, which were conducted over several months, the takeoff mode was repeatedly reached with the engine thrust reaching 35 tons. The obtained parameters and characteristics of the PD-35 exceeded the predicted values and confirmed the correctness of the selected technical solutions, which allows us to begin developing promising domestic high-thrust engines.
The competition work of the authors' collective "UEC-Aviadvigatel" "Automated system for development, management and publication of operational documentation in a single corporate environment" received the title of laureate in the nomination "For an effective system of after-sales service for Russian-made aviation equipment".
For the first time in the history of the Russian aviation industry, an automated system for issuing interactive electronic technical manuals in a single corporate PLM system has been developed and implemented. The Perm development allows for the creation of manuals in accordance with the requirements of the S1000D standard and can be adapted to customer requirements.
The new automated system developed the necessary materials for the cruise power plant with the PD-14 engine, which were transferred to aircraft manufacturers. As a result, the certification tests of the MS-21 aircraft with the PD-14 engine are provided with world-class electronic documentation.
In addition, specialists from UEC-Aviadvigatel have issued an operating manual for the serial PD-14 and developed materials for an illustrated catalog of parts and assembly units for the cruise power plant with the PD-14 engine. Materials for the PD-8 engine have also been developed and transferred. New manuals for the PS-90A, PS-90A-76, PS-90A1 engines and their modifications are also being issued in the new electronic documentation development system.
The award ceremony for the winners and diploma holders of the Aircraft Builder of the Year competition was held in Moscow. The awards were presented to the Perm designers by Deputy General Director, General Designer of UAC (part of Rostec) Sergey Korotkov and Senator of the Russian Federation, Deputy Chairman of the Federation Council Committee on Budget and Financial Markets Andrey Epishin.
The Aircraft Builder of the Year competition has been held since 2011. In 2024, 59 organizations applied for the award. The jury, consisting of more than 100 experts, reviewed 120 works and determined the winners in 10 nominations.

by the way, it comes in any number of configurations. Aircraft makers don't decide on seat configurations, the airlines do. Aircraft makers just propose some different configurations as part of its sales pitch.
by the way as a form of comparison, some 787-900 numbers
61.81m long, 60.12m wingspan, 17.02m high, fuselage cabin width is 5.49m and external width is 5.77m
MTOW is 254.7t
max payload 53t
so in comparison, C929 is 1m longer in total length
3m longer wingspan
MTOW is 7t lower
payload is 2.5t lower
it's disappointing they didn't post empty weight or fuel capacity
But certainly it seems like if the MTOW is lower with similar payload, my guess is that the empty weight is lower. And it would need to be lower to be competitive. Since new clean sheet are always expected to have lower operating cost in order to gain shares.
it's also 1m longer, which should allow 1 extra row of seat to be added, so that helps the economics calculation too.

The first prototypw likely will appear in 2027 or later.
Too bad fuselage width and cabin width weren't given. I tried to measure those from the graphics given, but I assume those aren't very precise to begin with. Anyway, for whatever it's worth, measuring the pixels, I am getting some 6.16 m fuselage width and 5.73 m cabin width. Still, those widths are a bit suspect, as neither b787 nor a350 are that wide. (a350 fuselage width 5.96 m) For a plane with stated MTOW, it's a bit strange they'd make it as large and wide.
We do have this from a little while ago but it's unclear if it remains the final specifications they're going with.
