Damage tolerance and notch sensitivity of bio-inspired thin-ply Bouligand structures

Composites Part C: Open Access, 2021
Different bio-inspired Bouligand thin-ply Carbon-Fibre-Reinforced Plastic (CFRP) laminates with a pitch angle as low as 2.07∘ are realised, which is the smallest pitch angle realised in literature.

Wind Turbine Power Curve Design for Optimal Power Generation in Wind Farms Considering Wake Effect

Energies, 2017
In modern wind farms, maximum power point tracking (MPPT) is widely implemented. Using the MPPT method, each individual wind turbine is controlled by its pitch angle and tip speed ratio to generate the maximum active power.

PITCH-ANGLE SCATTERING OF ENERGETIC PARTICLES WITH ADIABATIC FOCUSING [PDF]

The Astrophysical Journal, 2014
Understanding turbulent transport of charged particles in magnetized plasmas often requires a model for the description of random variations in the particle's pitch angle. The Fokker-Planck coefficient of pitch-angle scattering, which is used to describe scattering parallel to the mean magnetic field, is therefore of central importance.

Influence of Longitudinal Static Stability on Pitch Attitude Control Quality of Micro Air Vehicle

Nanjing Hangkong Hangtian Daxue Xuebao
The fixed‑wing micro air vehicle （MAV） is characterized by low speed and small moment of inertia， which make it susceptible to significant changes in angle of attack due to atmospheric disturbances during flight.

Conceptual study on using Doppler backscattering to measure magnetic pitch angle in tokamak plasmas

Nuclear Fusion
We introduce a new approach to measure the magnetic pitch angle profile in tokamak plasmas with Doppler backscattering (DBS), a technique traditionally used for measuring flows and density fluctuations.

Experimental Study on Efficiency of Floating Vertical Axis Wind Turbine with Variable-Pitch

한국해양공학회지, 2018
This paper presents the efficiency of a floating vertical axis wind turbine with variable-pitch. A model was designed to use the lift force and drag force for blades with various pitch angles. The blade's pitch angle is controlled by the stopper.
