The crew size varies up to 4 people.
The development of the life support system for the Russian lunar spacecraft PTK NP (crewed transport spacecraft of the new generation) has been completed. It is also referred to in the media as "Oryol."
This was announced by Alexander Tsygankov, the general director of the Scientific Research and Design Institute of Chemical Engineering.
"The life support systems are ready. Their purpose is the same as that on the International Space Station, only simpler," he said.
According to him, the spacecraft will be equipped with a toilet for cosmonauts to collect urine during the flight. A unit for heating water will also be installed on the spacecraft.
In the near future, the life support systems will undergo interdepartmental testing of the lunar spacecraft, Tsygankov noted. In addition, the institute is ready to adapt the systems for other crewed objects upon the customer's request.
The PTK NP spacecraft will transport people and cargo to space stations in low Earth orbit, and its development is part of the Russian lunar program. The vehicle is expected to replace the crewed "Soyuz" spacecraft. It can remain in the orbital station in low Earth orbit for up to a year and up to 180 days in a lunar station. In orbital mode, the spacecraft can fly autonomously for up to 30 days, and in lunar mode for up to 10 days.
Thanks to new composite materials and aluminum alloy 1570C, the spacecraft will be lighter and stronger than if it were made from the same materials as the "Soyuz". Like the "Soyuz" spacecraft, the "Oryol" will have a mixed landing system: parachutes and braking engines, allowing it to land within a radius of 5 km. However, unlike the "Soyuz," the "Oryol" is planned to use 3 braking and 3 main parachutes. In the event of a failure of one of the parachutes, the possibility of a safe landing must be maintained. The "Oryol" will receive the "Kurs-L" docking system from the "Soyuz" spacecraft.
