A propulsion system for creating a propulsive force has a combustion chamber, a pair of electrodes within the combustion chamber and a power supply attached to the electrodes to create a high voltage field within an initiation zone of the combustion chamber, and an injector for introducing a propellant, preferably in atomized form, into the high voltage field for creating the propulsive force. The fixing chassis unit has a fixing chassis body and a first fixing retaining structure disposed on a first lateral wall of the fixing chassis body. The device under test can be a system-on-a-chip integrated circuit, a mixed signal integrated circuit, a digital integrated circuit, or an analog integrated circuit. Additionally, an average displacement of the CMTL is computed. Appropriate ones of the devices described above may also advantageously be employed in wood, composite, and other bats. The configuration of this system allows a remote operated vehicle or any other launched load to be firmly captured until it is delivered to the desired destination.
