A generator coupling an EDFMG containing an 8.75 cm 3 of magnetic material with a spiral vector inversion generator yielded a pulse of amplitude over 40 kilovolts with a rise time of 6.2 nanoseconds. [4] Generators delivering pulses over 50 kV and 5 kA were demonstrated. [5] Ultra-compact generators with diameter less than 50 mm were developed.
The convergent cylindrical shock wave unleashed by the explosion produces a rapid contraction (greater than 1 km/s) of the central cylinder, compressing the magnetic field, and creating an inductive current, as per the explanation above (the speed of contraction permits, to first approximation, the neglect of Joule losses and the consideration ...
The wave-disk engine has the potential for better energy efficiency compared to conventional internal combustion engine designs and can potentially save weight. Possible applications include charging batteries in hybrid vehicles , which could reduce weight by about 1,000 pounds (450 kg).
This blast wave increases the temperature and pressure of the driven gas and induces a flow in the direction of the shock wave but at lower velocity than the lead wave. The bursting diaphragm produces a series of pressure waves , each increasing the speed of sound behind them, so that they compress into a shock propagating through the driven gas.
A shock tube detonator is a non-electric explosive fuze or initiator in the form of small-diameter hollow plastic tubing used to transport an initiating signal to an explosive by means of a shock wave (also known as a percussive wave) traveling the length of the tube. [1] Shock tube is used to convey a detonation signal to a detonator. Shock ...
According to the team that created the device, the vibrations from the heart muscles would be enough to allow the generator to power a pacemaker. [2] This would eliminate the need to replace the batteries surgically. In 2012 a group at Northwestern University developed a vibration-powered generator out of polymer in the form of a spring.
The BK Precision model 4078 Dual Channel Arbitrary Waveform Generator uses direct digital synthesis to generate waveforms up to 400,000 points HAMEG HMF 2550 digital AWG under an oscilloscope displaying the generated waveform. An arbitrary waveform generator (AWG) is a piece of electronic test equipment used to generate electrical waveforms.
A Stirling radioisotope generator (SRG) is a type of radioisotope generator based on a Stirling engine powered by a large radioisotope heater unit. The hot end of the Stirling converter reaches high temperature and heated helium drives the piston, with heat being rejected at the cold end of the engine.
