Control of recoil losses in nanomechanical SiN membrane resonators [PDF]
Physical Review B, 2016 In the context of a recoil damping analysis, we have designed and produced a membrane resonator equipped with a specific on-chip structure working as a "loss shield" for a circular membrane. In this device the vibrations of the membrane, with a quality factor of $10^7$, reach the limit set by the intrinsic dissipation in silicon nitride, for all the ...

Feasibility Analysis of Magnetorheological Absorber in Recoil Systems: Fixed and Field Artillery
Frontiers in Materials, 2020 Magnetorheological (MR) absorbers in the artillery recoil systems are usually used to dissipate the impact energy as much as possible and reduce the recoil force transmitted to the artillery carriage, while the firing stability of artillery during the ...

Control of a Soft Recoil System for Recoil Force Reduction [PDF]
Transactions of the Korean Society for Noise and Vibration Engineering, 2008 A fire-out-of-battery(FOOB) mechanism, which is a new recoil technology, can reduce dramatically the level of a recoil force compared to the conventional recoil system. The FOOB mechanism pre-accelerates the recoil parts in direction opposite of conventional recoil before ignition.

Control moment gyroscope recoil stabiliser including LQR controller for two-wheeled robot
International Journal of Heavy Vehicle Systems, 2023 The control moment gyroscope’s (CMG) success in emerging damping control under impact load is of great interest for new technical applications. This paper explores the potential use of a two-wheeled robot with an independent weapon, such as an automatic cannon robot, and considers employing CMG with LQR control as a weapon recoil stabiliser for the ...

Suppressing Recoil Heating in Levitated Optomechanics Using Squeezed Light
PRX Quantum, 2023 We theoretically show that laser recoil heating in free-space levitated optomechanics can be arbitrarily suppressed by shining squeezed light onto an optically trapped nanoparticle.

Recoil reduction method of gun with lateral nozzle controlled by electromagnetic valve
Journal of Physics: Conference Series, 2021 Abstract A new recoil reduction method of gun was proposed in this work to reduce the recoil without reducing the muzzle velocity and changing the continuous firing mode. Its recoil reduction mechanism was studied based on the two-phase flow theory.
