These components exchange information such that a change in
one component automatically propagates through the entire assembly
to always result in a valid design.
The entire process took only minutes to run and completely
reengineered the Aerospike design from scratch to conform to
the new specifications. The engine was printed on the EOS M
400-4 industrial 3D printer with zero support using the EOS
NickelAlloy IN718 process. A larger 80-cm version of the aerospike
was automatically reengineered for production on the
AMCM M 4K 3D printer in EOS CopperAlloy CuCrZr.
Both engines feature many interesting design aspects. Multiple
combustion chambers enable thrust-vectoring. The chambers'
cross-sectional areas are driven by a desired Mach number distribution
and calculated through the isentropic flow conditions.
Algorithmic Engineering enabled regenerative, dual-propellant
cooling circuits to be automatically routed across the walls of
the individual combustion chambers. The injector head consists
of mass-customized co-axial swirl injectors. Each injector element
is optimized based on its distance to the wall for a given combustion
temperature distribution. All manifolds and internal routings
adapt their local overhang angles to ensure printability, by dynamically
changing their cross section between round (vertical print
orientation) and rhombic (horizontal print orientation).

Using High-Resolution X-ray
Computed Tomography to Inspect Additive
Manufactured Parts
Additive manufacturing (AM) techniques are quickly replacing conventional " subtractive " machining
for producing low volumes of complex parts. X-ray micro-computed tomography (µCT)
is the only technique that gives a full three-dimensional quantitative picture of the structure of
a part, both internal and external, showing density variations, dimensional mismatches, voids,
and inclusions, and allows accurate measurements of these to be made.

" This Algorithmic Engineering approach is a game changer
for innovation in physical objects because of its ability to generate
fast engineering cycles, " said Josefine Lissner, Strategic Engineering
Lead at Hyperganic. " I expect it to be the next disruption
in the space industry, where progress is hampered by the
prohibitively high cost of design iterations. Once a company establishes
this new process successfully, it will be impossible for
competitors to keep up using a manual CAD approach. "
Rocket engines are by far the most expensive part of an
entire launcher, as the development process requires a lot of
time, money, and human labor. Hyperganic's platform enables
engineers to accelerate the design process by using existing
software modules without any manual involvement,
thus dramatically decreasing the cost of space travel. Through
Algorithmic Engineering, the space sector can now build novel
propulsion systems like the Aerospike concept in less time
with less money.
This new engineering paradigm is not limited to space propulsion
but also relevant to all other engineering domains, including
industrial and automotive applications, heating and cooling,
bio-printing, and next-generation consumer products.
