Irtysh(Russian:Иртыш),[2]also namedSoyuz-5(Russian:Союз-5), formerly codenamedFenixin Russian andSunkar(Kazakh:Сұңқар,lit. 'falcon') in Kazakh, is a planned Russianrocketthat is being developed byJSC SRC Progresswithin the "Project Feniks" (Russian:Феникс,lit. 'phoenix'). Initially it will replace the capability ofZenit-2andProton Medium,and in the future will serve as the base of asuper heavy-lift launch vehiclerocket (Yenisei) to match theEnergia/Burancapabilities. As of August 2023[update],Irtysh is expected to launch from theBaikonurBaiterek,the ex Zenit-2 launch site, in a partnership with the government of Kazakhstan, with a planned debut in December 2025.[1][3]
Project organization[edit]
The current proposal is led byJSC SRC Progress,with support byKhrunichevandMakeyev,additionally,RSC Energiawould handle the launch site, and supply theBlok DM-03,whileRoscosmoswould finance the development through the Project Fenicks under the 2016–2025 Russian space master plan.KazCosmoswould also be a partner since the initial launch pad would be atBaikonur CosmodromeSite 45in Kazakhstan, within the framework of the Baiterek bi-national joint venture, andInternational Launch Services(ILS) would commercialize its services for the international market.[4][5]
The initial application of the launch vehicle would be to cover the under 5 t (5.5 tons) toGTOcommercial launch segment. With the loss of theZenit-3SLBdue to Russian conflicts with Ukraine, both the decision not to developAngara A3and launchAngara A5fromVostochny,the Baiterek project was without a launch vehicle. The 2016 announcement of theProton Medium and Lightmeant that ILS could enter the medium GTO launch market, but since the Kazakh government desired to deprecate the use of highly toxichypergolicpropellants used by Proton, they would need a replacement.[4][5]
For this commercial application, JSC SRC Progress proposed the Soyuz-5 in early 2016. It would start with this commercial application with the prospect of also enabling a super heavy launcher with a 80 t (88 tons) payload capability tolow Earth orbit.[4][5]The Kazakh side agreed on the general terms, but the investment share was left to decide. As part of the 2016 arrangements, the Kazakh government would get ownership of one of the Proton launch pads, and participate in the operations of Proton-Medium and Proton-Light.[6]Then, they would get to participate in the Irtysh launchers since its expected debut in 2024.[3]As of August 2023 further delays in the construction of the launch site and in the development of the rocket pushed the date of the maiden flight to December 2025.[1]
Four test launches are planned before the development is considered complete.[7]
Development of the Irtysh is expected to face delays, as the necessary modification of the launch pad atSite 45for launching the Irtysh has been delayed, starting only in late 2021.[8]International sanctionsfollowing theRussian Invasion of Ukrainefurther slowed operations. In July 2022,Dmitry Rogozin,then CEO ofRoscosmos,admitted that construction would be postponed by six months to one year.[8]
In March 2023, it became public that the BaiterekKazakh-Russianjoint venture in charge of the site had seized the facility after filing a claim of about 2 billionrubles(30.3 millionUS-Dollar) to TsENKI, aRoscosmossubsidiary in charge of handling ground-based infrastructure, as Roscosmos had failed its obligation to conduct an environmental impact assessment of Site 45, causing additional delays.[9]
Vehicle[edit]
Soyuz-5,as proposed in 2016, leverages existing propulsion and tooling, while enabling a platform that would replace the lost capabilities of theZenit family,replace theProton Light/Medium,and could serve as the boosters of a new super heavy rocket. It will initially be a two-stage rocket, but could be enhanced with an optionalBlok DM-03forgeostationarymissions. It would be compatible with most of the Zenit's ground infrastructure, and even use theSite 45atBaikonur.[5]
Its tanks would be 4.1 m (13 ft) in diameter, which would enable the re use of Proton tooling. Since they would be wider than Zenit, (3.9 m (13 ft)) it would enable a higher propellant load for the same height. While this diameter enables a heavier rocket and is already compatible with train transport to Baikonur, it would prevent that method of transport forVostochny Cosmodrome.It would use the relatively environmental friendlyRP-1/LOXpropellant, which would be an improvement over the highly toxichypergolicsof Proton. This has been a requirement from the Kazakh government for new projects.[4][5]
The first stage would be powered by anRD-171MV,very similar to the RD-171M used in Zenit 2 and 3. With a height of 37.14 m (121.9 ft) it would be higher than Zenit's first stage (32.94 m (108.1 ft)) and wider, and thus it could carry 363 t (400 tons) of propellant versus 290 t (320 tons). Its base would still feature a 3.68 m (12.1 ft) aft section for compatibility with Zenit's pad and support infrastructure.[4][5][10]
Its second stage would measure 7.77 m (25.5 ft) by 4.1 m (13 ft) in diameter, with a dry mass of 5.9 t (6.5 tons) and an RG-1/LOX load of 59 t (65 tons). It would be powered by twoRD-0124MSengines, each having four nozzles arranged in a semicircle. So, two engines would feature eight total nozzles close to the rocket perimeter, forming a circle. This arrangement would minimize the stage length, while keeping the engines' excellentspecific impulse.[4][5][10][11]
With a gross mass of 484 t (534 tons) against Zenit 430 t (470 tons), and the improved efficiency of its second stage, it could launch 16 t (18 tons) to a 200 km circular orbit with an inclination of 51.6° to the Equator from Baikonur. This is a significant improvement over Zenit, which could only place roughly 12 t (13 tons) to the same orbit.[4][5][10][12]
Forgeostationarylaunch missions, it could optionally be equipped with aBlok DM-03third stage. Since it would use the same propellant and is already used on theZenit-3SLandAngara A5,it would be a low risk option.[4][5]The expected performance of 4.5 t (5.0 tons) toGTOand 2.3 t (2.5 tons) toGSO,it would improve over Zenit-3SLB 3.6 t (4.0 tons) and 1.59 t (1.75 tons).[5][13][10]
Soyuz-5 Super Heavy (Yenisei)[edit]
The Irtysh first stage could be used as the boosters (and even core) of thesuper heavy rocketYenisei capable of launching 73 t (80 tons) tolow Earth orbitfrom Baikonur or Vostochny. Improving the performance to 120 t (130 tons) and even 160 t (180 tons) was considered possible with this architecture. While the current 2016-2025 plan fordeep space explorationcalls for the use of the heavyAngara 5V,it would just enable 36 t (40 tons), requiring up to four launches for a single Moon mission, and would also require the use of expensive hydrogen as fuel. The Yenisei would simplify the mission while using readily available Irtysh first stages.[14][5][10][12]
