This paper highlights the design work for optimized dynamics, aerodynamics, flying and handling qualities taking into account the experiences gained during the development of the EC135. First a brief description of the development schedule and helicopter is given. Then follows a discussion of interesting topics like rotor dynamics, vibration, rotor/airframe aerodynamics, stability and control. For each problem area, significant parameters are discussed and tendencies are shown. In addition, the methodology used today in the design process of a helicopter is addressed. Results show a wide range of interesting numerical values of design parameters or system qualities like rotor stiffness, pitch-lag coupling of the BMR blades, endplate/stabilizer configuration, cabin vibrations, maneuverability, controllability, influence of lateral derivatives on Dutch roll damping and optimized gust response. All discussed items are reflected by flight test results.
