About
Peretz Friedmann is a Professor Emeritus in the Department of Mechanical and Aerospace Engineering at UCLA Samueli School of Engineering. His research interests include helicopter and fixed-wing aeroelasticity, active control of helicopter vibration and noise, aeroelasticity and aerothermoelasticity of hypersonic vehicles, unsteady aerodynamics, and optimization with aeroelastic constraints. He also focuses on structural dynamics and the aeroelasticity of flapping wing micro air vehicles (MAVs). His work involves studying the complex interactions between aerodynamic forces and structural responses in various aerospace applications, contributing to advancements in vibration control, noise reduction, and the design of high-speed and bio-inspired flight systems.

Journal of Fluids and Structures · 2020 · 32 citations
Senior authorCorrespondingAeromechanics and Aeroelastic Stability of Coaxial Rotors
Journal of Aircraft · 2021 · 19 citations
Senior authorCorrespondingCoaxial rotor aeroelasticity is complex due to the counter-rotating wake system, rotor lift offset, periodic blade passage loads, unsteady rotor wake interactions, reduced rotor speed, and stiff hingeless blades. In this study, the aeroelastic stability of a coaxial rotor is examined in hover and forward flight. The rotor wake is modeled with the viscous vortex particle method, a grid-free approach for calculating vortex interactions over long distances. The spanwise blade aerodynamic loading is…

Helicopter Shipboard Landing Simulation Including Wind, Deck Motion and Dynamic Ground Effect
Journal of Aircraft · 2020-10-31 · 15 citations
articleSenior authorA first principles physics-based simulation framework that accounts for wind-over-deck (WOD) and ground effects during approach and landing of a helicopter on a ship deck is developed. The WOD velocities are obtained from unsteady detached-eddy simulation of the flow over a simple frigate shape version 2 ship. The HeliUM2 flight dynamics code was modified to include WOD, static and dynamic ground effects, and landing gear models. A dynamic ground effect model that combines a finite-state wake mo…
