Rocket Lab Reveals First Battery-Powered Rocket for Commercial Launches to Space
- First-of-its-kind technology to offer affordable, high-frequency launches of small satellites
- Engine created through 3D printing and using electric turbopumps
Rocket Lab, the rapidly growing aerospace company, today unveiled the Rutherford engine, revealing that the Electron launch system is the first battery-powered rocket.
Electron is a small orbital launch vehicle, designed to transform the global space industry with affordable, high-frequency launches of small satellites.
“Historically, the time and expense to launch small satellites have been prohibitive, costing many millions of dollars and requiring endless patience and flexibility waiting for months to ‘hitch a ride’ to space,” said Peter Beck, CEO of Rocket Lab. “With Electron, companies can launch whenever they would like, at a substantially more affordable cost. This monumental advancement in space technology gives satellite-reliant businesses the freedom they have been waiting for, which will lead to vast improvements in how we use satellite technology in space.”
Electron features announced today:
- Electric Rutherford engine. Unlike traditional propulsion cycles based on complex and expensive gas generators, the 4,600 lbf Rutherford adopts an entirely new electric propulsion cycle, making use of high-performance brushless DC electric motors and lithium polymer batteries to drive its turbopumps.
- 3D printed primary components. Rutherford is the first oxygen/hydrocarbon engine to use 3D printing for all primary components including its engine chamber, injector, pumps and main propellant valves. Using this process, Rocket Lab’s engineers have created complex, yet lightweight, structures previously unattainable through traditional techniques, reducing the build time from months to days and increasing affordability.
- Payload integration. Electron’s upper stage is designed with the capability to disconnect the payload integration from the main booster assembly. Sealed integrated payloads can then be transported back to Rocket Lab where integration with the main booster can occur in a matter of hours. This approach eliminates the risk of cascading delays and allows customers to regain control of the integration process, using their own preferred facilities and personnel.
“Although the privatization of the space industry has promised an easier path to commercial launches, space has remained an incredibly difficult and expensive place to reach,” said Beck. “Electron makes it possible for us to continue to execute on our vision to enable easier access to space. As more small satellite companies are able to quickly reach orbit, we will see immense advancements in communication and imaging technologies, which has the potential to drastically change our world – from improved traffic reporting to crop planning to even mitigating the life-threatening damages of natural disasters.”
