At the 30,000 lbf thrust level, this engine is ideal for the rapidly growing small launch vehicle and low-cost upper-stage markets. This latest milestone paves the way for

The 30,000 lbf thrust-class engine, which would normally be comprised of over 100 parts, is built from only three additively manufactured major components: the injector assembly; the combustion chamber; and a throat and nozzle section. These three major components are welded together to form a single thrust chamber assembly.
"The demonstration of a regeneratively cooled, high-chamber-pressure engine made completely with 3-D printing is another key milestone in Aerojet Rocketdyne's path to reducing the cost of rocket propulsion systems," added Littles. "Printing the part is not the hard part, it is printing parts that can provide the performance and reliability that our customers depend on that is the key."
The Bantam engine was designed, fabricated and tested in just seven months at a fraction of the cost of producing the engine using traditional fabrication methods. Its recurring price would also be a fraction of the cost of today's products.
"The new generation of product aims to help change the economics of space access that is critical to our warfighter, civil and commercial customers," said Littles.
"The results of this test program confirm that we are on the
right path to take advantage of the advancements we've made in 3-D printing technology as a key part of our strategy to deliver more affordable products to our customers while we maintain the reliability they've come to expect," said
