Radian Aerospace, based in Seattle, has successfully completed low-speed ground taxi testing for a prototype aircraft in Abu Dhabi. This prototype is a subscale version of the full-scale Radian One space plane they are developing. The prototype, powered by two jet engines, performed a series of maneuvers and reached speeds of around 50 knots during testing. The company aims to transform access to space with a rapid, reusable, and cost-effective transport system to low Earth orbit.
The prototype tested in Abu Dhabi, known as AV09, is one step in the design process for the full-size Radian One. The design team is currently working on AV12 and will begin the design cycle for AV13 soon. Radian One is intended to carry two to five crew members and transport 5,000 pounds or more to low Earth orbit. It could be used to transport crew and cargo to the International Space Station, deploy satellite payloads in orbit, provide point-to-point transportation, or be used for hypersonic flight applications desired by the U.S. military.
Radian One will utilize a rocket-propelled sled and methane-fueled rocket engines for launch. The company is partnering with others who are working on a LOX-methane solution, rather than developing it themselves. Various tests and developments for the space plane, such as wind tunnel testing and the thermal protection system, are underway in locations such as the U.S. Air Force Academy and NASA’s Glenn Research Center. Radian Aerospace is also developing carbon-composite tanks in collaboration with the University of Washington and Janicki Industries.
Radian Aerospace recently raised $27.5 million in funding, which may not be sufficient to launch the full-size Radian One. As a result, testing of the prototype was conducted in Abu Dhabi as part of the United Arab Emirates. Holder noted strong interest from potential investors and users in the region, indicating the global appeal of the program. The company intends to have Radian One operational by 2029 or 2030 to provide transport services for commercial space stations that will succeed the International Space Station.
Radian Aerospace has engaged with multiple commercial space station developers, building relationships and discussing potential transportation options. Despite not being as well-known as companies like SpaceX, Radian Aerospace aims to compete by providing a cost-effective and operationally efficient transportation solution. The team is focused on garnering support and recognition within the space industry to establish themselves as a viable player in the commercial space transport sector. Holder emphasized the positive interactions they’ve had with various stakeholders in commercial, civil, and government space sectors.
In conclusion, Radian Aerospace’s ground taxi testing of the prototype aircraft in Abu Dhabi marks a significant milestone in their journey to develop the Radian One space plane. The company’s innovative approach to space transport, collaboration with partners, and strategic development timeline position them to potentially provide transportation services to future commercial space stations. With continued testing, funding, and partnerships, Radian Aerospace aims to establish itself as a key player in the commercial space industry, offering a competitive and reliable transport option to low Earth orbit.
