Russian rugged attritable ugly thing.RIA Novosti has received footage of ground tests of the new TRAMP transport drone (multifunctional transport platform for transport aviation).
Earlier, a RIA Novosti source at the military-industrial complex reported that the drone is capable of transporting up to 250 kg of cargo over a distance of more than 600 kilometers. One of the features of the machine is a large cargo compartment with a volume of 2650 liters, which allows you to transport gross cargo and drop it with a parachute to a certain point.
speed of the vehicle is 195 km / h, the starting ceiling is 3 km. The first flight of the prototype is scheduled to begin in April.

I have not heard of anything about this before.The Federal Air Transport Agency has approved a modification of the standard design of the Perm PD-14 engine. The main parts of the compressor and the high-pressure turbine will be produced according to new designs..
don't know why they are changing the main components of PD-14 engine. maybe @gelgoog can tell us.
I have not heard of anything about this before.
Are you sure that is what they are saying? It seems more like they are switching the main supply of metal blanks to the compressor and high-pressure turbine rather than any design change.
There was a recent news report regarding changes to the design of the compressor and high-pressure turbine for the Al-222 engine to make it easier to manufacture and lower maintenance though. But that is an engine design by a different engine company, Klimov, which was originally based on a Ukrainian design.
The improved product has improved weight and size characteristics, and also simplifies the repair and operation of the power plant.
“The first tests of a prototype that took place at the enterprise confirmed the operability of the design. The gas generator with the new HPC worked without comment on the test bench. This is a great success, which will be the starting point for using this unit in a modernized engine, ”said Alexey Gromov, head of the Salyut Production Complex of JSC UEC .
In the course of work on the modernization of the AI-222-25 engine, the experience of operating a serial power plant is taken into account. This will improve its characteristics and expand the possibilities of operation on various aircraft.
In the future, the high-pressure compressor will undergo a series of new tests.
If in 2022 the enterprise manufactured five sets of self-propelled guns for the PD-8, then this year it is planned to produce about 35 sets.
“Experimental design work on the SAU-8 for the PD-8 engine will be completed in June this year. Currently, preliminary and qualification tests of the units are underway, including for climatic, mechanical and other external influences. After that, the aircraft with PD-8 engines will complete the flight qualification test program, and the Perm units will be assigned the letter O1 - they will move from experimental to serial status, ”says Sergey Popov, managing director of UEC- STAR .
The average SSJ for this parameter at Red Wings in the summer and autumn of last year
The plan for the summer of 2023 is 350-370 hours per month. It's a lot.
“In good hands, the Superjet is a true workhorse and has excellent flight records. This suggests that domestic aircraft can fly no worse than Boeing with Airbus ,” said Vladimir Artyakov, First Deputy General Director of Rostec.
