Numerical Study of Reverse Thrust Generation Using Co-Flow Jet
This paper studies a new reversed thrust generation method for airfoils by use of active flow control altered from the regular Co-Flow Jet (CFJ) airfoil. This reverse thrust is generated by a CFJ injection slot duct that is redirected to flow against the

Closed-loop Flow Control Method Based on Deep Reinforcement Learning using a Co-flow Jet [PDF]
A closed-loop control framework is developed for the co-flow jet (CFJ) airfoil by combining the numerical flow field environment of a CFJ0012 airfoil with a deep reinforcement learning (DRL) module called tensorforce integrated in Python.
