Reliability of Time-Linearized Flutter Predictions Near the Surge Line [PDF]
In the context of the flutter analysis of a modern transonic axial compressor two different CFD codes have been compared: based on the same three-dimensional steady solution, the timelinearized Navier-Stokes flow solver TRACE of the German Aerospace ...

The Future of Research in Cognitive Robotics: Foundation Models or Developmental Cognitive Models?
Research in cognitive robotics founded on principles of developmental psychology and enactive cognitive science would yield what we seek in autonomous robots: the ability to perceive its environment, learn from experience, anticipate the outcome of events, act to pursue goals, and adapt to changing circumstances without resorting to training with ...

AEROELASTIC FLUTTER ANALYSIS OF SUPERSONIC WING WITH MULTIPLE EXTERNAL STORES
: Flutter may be considered to be one of the most dangerous aeroelastic failure phenomenon. The flutter characteristic differs for each aircraft type, and depends on the wing geometry as well as its operational region of subsonic, transonic or supersonic

Numerical Modeling of Photothermal Self‐Excited Composite Oscillators
We present a numerical framework for simulating photothermal self‐excited oscillations. The driving mechanism is elucidated by highlighting the roles of inertia and overshoot, as well as the phase lag between the thermal moment and the oscillation angle, which together construct the feedback loop between the system state and the environmental stimulus.

Cable Flutter Analysis of ALFLEX.
This paper introduces the flutter phenomenon occurring in the automatic landing flight experiment for a Japanese unmanned space shuttle of HOPE-X. The experimental vehicle called ALFLEX which was a dynamically scaled model of HOPE-X was towed by one cable before its release. An oscillation was observed on the cable with release device during flights of

A computational procedure for automated flutter analysis [PDF]
AbstractA direct solution procedure for computing the flutter Mach number and the flutter frequency is applied to the aeroelastic analysis of propfans using a finite element structural model and an unsteady aerodynamic model based on a three‐dimensional subsonic compressible lifting surface theory.

A flexible, skin‐integrated electromagnetic actuator is developed for wearable virtual/augmented reality (VR/AR) haptic systems. A tunable design model enables control over displacement and resonance frequency. The system is validated through a custom VR application with a 6 × 4 actuator array, demonstrating real‐time, spatially targeted tactile ...
