About
Arjun Krishnan is a researcher whose work lies at the critical intersection of rotorcraft dynamics and innovative mechanical design. His primary research areas include crashworthiness, active vibration control, and the development of novel landing gear systems for helicopters. Krishnan’s most notable contribution is the design, manufacture, and testing of a crashworthy cable-driven four-bar link robotic landing gear system, detailed in his 2019 paper (9 citations). This work demonstrates how combining two such mechanisms via a common driving cable yields unique kinematic advantages, directly enhancing rotorcraft safety during hard landings. Building on this foundation, his 2021 study (2 citations) explores the suppression of ground resonance—a dangerous mechanical instability caused by coupling between rotor lead-lag motion and the airframe—using actively controlled landing gear. By examining the fundamental control aspects of this instability, Krishnan’s research paves the way for smarter, more adaptive landing systems that can actively mitigate structural vibrations. His work represents a significant step forward in making rotorcraft both more resilient to crashes and more stable on the ground, blending practical mechanical engineering with advanced control theory.
