The   German company Hyperganic,which  we  met   last  year,   recently  presented  its prototype  3D-printed  rocket   engine, designed  entirely  using  artificial intelligence.  The entire  room was  designed  in  a  single  block,  incorporating both   the combustion chamber and the surface channels.  Instead  of having  a CAD file,  the   modeling information  would be  entered  according to  a  formula  readable  by  Hyperganic‘s algorithm.  .  This one  could  then  use  the  data  to  design the final piece, from bottom to  en  top.. 

Combining additive manufacturing with  artificial intelligence can  generate   key benefits  for  the industry:   a  3D printer with  AI could  reduce  the  risk of error,offer  automated production,  Etc. In the  case  of  Hyperganic  l’intelligence  here,  artificial intelligence can design the object   directly.  une Duy-AnhPham, the German   company’s  design  manager, explains:    “We  compare  this  process  to  growth rather than   design. You  tell  the algorithm  what   you  want   en   the object to     do,  and then the algorithm makes the object grow  based on  the  performance and  specifications you  had  at Mind.  Thus,the  process  does not create  a plane,  but  the DNA of an  object.”

The process  of making the   rocket engine

Hyperganic’s goal  was   to design  a   single-block  rocket engine  to have  the   lowest possible weight and the  most  efficient cooling. .  Traditionally,the  different  components of a   rocket engine  are  designed  separately;   then,we  come  to weld  the  cooling  channels  to the combustion chamber.   But  this  can  cause long-term  errors and  explosions. With  this  manufacturing method,  Hyperganic  would be able to design    everything  in  one block,  then increasing the final performance of the  engine..  The company   therefore  took  into  account  the  key elements of the  engine,  namely the combustion chamber and cooling  channels:  on the basis of  this  data,an  algorithm  generated  a  geometry  meeting   all  these  specifications..

 The company  then 3Dded  a first  metal  prototype from a nickel alloy.   Duy-AnhPham  adds:    “We  are able to  print  in different densities of  materials,   a  method  that  has not yet  been  used in the design of  rockets. The  inner part  is  thus   very  solid,  while  outward,  the structure  becomes  more  porous  to  gain weight..  Every extra  kilo  counts..   “Indeed,  the  launch of a  rocket representing a certain  cost,  reducing its overall weight   even a few kilos has a significant impact. . 

Hyperganic would work  with  several   aerospace  companies to see  how  to integrate  this  new   modeling approach  into  their  operations. The  use of artificial intelligence  would allow  them to imagine   completely  new forms  in order  to  reduce the weight  of  the  parts  and  increase  their  performance. The  German company hopes  to go  further  in  terms  of applications,  claiming  that  its software  solution  is  modular,  offering multiple algorithmic combinations.  You  can  find  more  information on its  official website. .
