Performance Comparison of Typical Electrothermal Actuators

Key Engineering Materials, 2013
As the power producer, the micro actuator is an important part of the micro electro- mechanical system, which is used as the conversion of energy, motion and force producing. In this paper, the mechanical models of three bent beam electrothermal actuators are summarized to make comparison with each other and analyze mechanical performance. For Π-shaped

Microwave electrothermal thruster performance in helium gas

Journal of Propulsion and Power, 1987
The microwave electrothermal thruster presented uses an internally tuned, single-mode cylindrical cavity applicator to focus and match microwave energy into an electrodeless, high pressure flowing gas discharge that is located within a quartz discharge chamber.

Setup and performance of a 105 mm electrothermal gun

IEEE Transactions on Magnetics, 1997
Within the France-German R&D programme on electric guns, a 105 mm electrothermal gun has been designed and fabricated to be fired in the 30 MJ facility "FEUER-STELLUNG 2000" located at the Rheinmetall proving ground in Unterluss. It was the goal to demonstrate the acceleration of 2 kg flight projectiles to up to 2500 m/s with this gun.

Electrothermal performance of CNTs/ATO composite film

Journal of Alloys and Compounds, 2019
Abstract The precursor solution of antimony doped tin oxide (ATO) thin film was prepared by sol-gel method using SnCl4·5H2O and SbCl3 as raw materials and anhydrous ethanol as solvent. Then modified carbon nanotubes (CNTs) were added to the precursor solution to form stable precursor suspension. CNTs/ATO composite films were deposited on clean quartz

Tunable Microwave Electrothermal Thruster Performance on Water

39th AIAA/ASME/SAE/ASEE Joint Propulsion Conference and Exhibit, 2003
Thrust, specific impulse, thrust efficiency, and microwave coupling efficiency were measured for a microwave electrothermal thruster (MET) operating on water in a non-tunable configuration, and on helium and water in a tunable configuration. In the nontunable configuration, attempts to improve water performance by repositioning the nozzle to counteract

Electrothermal performance of an activated carbon honeycomb monolith

Chemical Engineering Research and Design, 2012
Abstract The main advantage of Electric Swing Adsorption (ESA) process is related to the fast heating rates that can be achieved by Joule effect. Since this heating is done by passing electricity, its utilization should be efficient to reduce the overall losses of the system.

Electrothermal thruster performance with biowaste propellants

8th Electric Propulsion Conference, 1970
The environmental control systems of manned spacecraft will generate waste gases that can be useful for propulsion. Electrothermal thrusters using these gases can provide the impulse necess a ry for spacecraf t control and drag makeup. One promising biowaste thruster design uses a vortex heat exchanger. A coaxial wire-wound heater element i s contained

Effects of wet treatment on bonding strength and electrothermal performance of electrothermal plywood bonded with emulsion polymer‐isocyanate adhesive

Polymer Composites, 2022
AbstractTo create a green, safe, and aldehyde‐free indoor heating environment, an eco‐friendly emulsion polymer‐isocyanate (EPI) adhesive was applied to the preparation of electrothermal plywood with built‐in carbon fiber paper. The optimized process parameters of electrothermal plywood were 0.9 MPa, 120°C, 6 min, and 200 g/m2 for hot‐pressing pressure,

High Power Microwave Electrothermal Thruster Performance on Water

38th AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit, 2002
Thrust, specific impulse, thrust efficiency, and microwave coupling efficiency were measured for a nominally 1 kW microwave electrothermal thruster (MET) operating on He, N 2, and N 2O, and for a nominally 5 kW MET operating on water. For He, N 2, and N 2O thrust varied from approximately 100 to 700 mN at discharge pressures from 500 to 2000 Torr and ...

Modelling of Chevron electrothermal actuator and its performance analysis

Microsystem Technologies, 2018
In this work, a Chevron electrothermal actuator is designed and its analytical model is developed. Chevron actuator works on the principle of Joules heating effect and thermal expansion. Aluminum is chosen as a material for actuator because of its good electrical and thermal properties and also it produces large displacement of about 10.94 µm with ...
