General Information

1.1 Project Information

The recuperated Micro Turboshaft Engine (KATS-100R) research project launched
in  late 2015  is a basic technology R&D project led by  Korea Aerospace Research
Institute  funded  by  the  ROK  government.  This  project  initiated  by  the  needs  of
replacing reciprocate engines for small UAS by micro gas turbine engines. The goal
of the project is to develop two key engine components, recuperator and reduction
gearbox,  and  to  establish  an  engine  design  process  at  KARI.  KARI,  as  a  system
designer, will develop a rubber engine and shall provide components development
and installation requirements. The two components are under development and their
prototypes will be tested within two years. At the end of the project, KARI will make
a  physical  mockup  based  on  the  engine  design  result,  and  install  the  developed
recuperator and the reduction gearbox on it.

KARI  is  the  system  designer  and  leading  organization.  There  are  two  Korean
companies  to  develop  and  test  reduction  gearbox.  One  Korean  company  which
develop  recuperator  and  test  with  KARI.  Hanwha  Techwin  involves  as  a  layout
designer and lead engine detail design for the component installation purpose.

This technical consulting will support establishing a turboshaft engine designing
process in KARI and review preliminary engine design result for the project.
