Skyrora, Spirit AeroSystems collaborate to enhance future U.K. launch capabilities

Spirit’s aerostructures expertise will guide transition from development to full-scale production of Skyrora’s orbital launch vehicles, including the composites-intensive SkyLark L.

Private space company Skyrora Ltd. (Edinburgh, U.K.) and Spirit AeroSystems (Belfast, Northern Ireland) have announced a collaboration on orbital launch capability. The partnership will enable Skyrora to transition its orbital launch vehicles from development to full-scale production using Spirit’s highly adaptive manufacturing and testing solutions in metallics and composites, in addition to localizing its supply chain.

Skyrora is developing an agile, end-to-end, launch service to provide access to space for small satellites globally. Having conducted a test launch of the suborbital, single-stage Skylark L vehicle in October 2022 as part of the company’s incremental learning approach to launch, Skyrora says it is on track to become the first U.K. company to vertically launch satellites from the U.K., expecting to conduct up to 16 launches per year once operating at scale.

SkyLark L is 11.65 meters in length and 0.7 meters in diameter, with a payload mass of 50 kilograms. Like Skyrora’s Skyrora XL 22.7-meter three-stage, light class launch vehicle (read more on this below), the craft uses fiberglass, carbon and aramid fibers reinforced with polymers such as epoxy, vinyl ester and polyester resins.

“By collaborating with innovative partners like Spirit, Skyrora will be able to access manufacturing and testing capacity right here in the U.K.,” Volodymyr Levykin, CEO and founder of Skyrora, says. “Historically, space has not been an environmentally friendly industry, but we are committed to being a responsible player that continues to foster talent and skills nationally as the ambitious New Space economy goes from strength to strength.”

The three-stage launch vehicle’s modular design comprises three stages, a payload adapter and a payload fairing. The payload fairing casing is two halves of a three-layer composite shell with honeycomb filler. Bearing layers are carbon fiber. According to the company, a 10-layer composite shell with foam ribs has also recently been built. When the rocket reaches the required altitude, the halves of the payload fairing are released with the help of push-rod springs installed on the payload fairing casing. The third-stage propellant tanks of the launch vehicle incorporates carbon fiber prepreg overwrapped pressure vessels. Primary parts including interstage bays and the rocket’s high-pressure spheres also comprise composite materials. In addition, Skyrora conducted a 70-kilonewton engine test done with composite overwrap tanks (main body and spherical high pressure).

Spirit’s presence in U.K. space is growing. Its broad offering of manufacturing and testing solutions, at both its Scotland and Northern Ireland facilities, brings significant industrial capacity to Skyrora’s launch proposition. Leveraging Spirit’s aerostructures expertise, the companies will explore opportunities to transition Skyrora’s orbital launch vehicles from development to full-scale production.

The U.K. government has made orbital launch a key priority, with the National Space Strategy outlining plans to secure an increased portion of a global space economy expected to be worth £490 billion by 2030. “This collaboration between Skyrora and Spirit clearly demonstrates the attractiveness of the U.K.’s thriving launch sector and the growing interest from both U.K.-based and international companies,” Matt Archer, director of launch, UK Space Agency, adds.

Collaborative goals also include the research of space technologies, particularly in additive manufacturing. Skyrora will provide Spirit with access to Skyprint 2, claimed to be the largest in-house hybrid 3D printer of its kind in Europe. Located in Skyrora’s manufacturing facility just outside Glasgow, research enabled by Skyprint 2 has the potential to unlock a localized supply chain to reduce costs and lead times for Spirit, bolster industrial cooperation and promote growth within the U.K. space sector.
