Methodology of construction and models of informative signals for a stationary miltichannel flow aerometric receiver of the helicopter air data system

Multi-channel gas-diesel engine control system based on jet-convective sensors

“…The principle of operation of the gas fuel flow meter, built with the use of the JCT, is based on the dependence of the thermal power dissipated by the heated element from the flow of the flow that washes it [18]. Consequently, the thermal energy required per unit time to maintain a constant temperature difference between the heated element and the gas that washes it, is directly proportional to the mass flow rate through a given flow cross-section.…”

“…In the development of the module for measuring the mass flow of fuel components, despite the slight complication of algorithms for processing the primary informative signals, is the use of methods based on the use of a combination of different physical effects and principles of structural construction of processes of measuring transformation of mode parameters of automobile engine operation. A fundamental novelty in construction of the jetconvective module for measuring the gas fuel flow rate is the use of a new combination of basic physical effects (deformation of the gas flow in the jet and jet-convective interaction of the gas flow with the heated body), which allows expanding the measuring range of the flow rate of the measured medium by more than one order compared with the known analogues [18][19][20].…”

“…A distinctive feature of the ECS structure implemented in the project is the use of jet convective transducers as part of the measuring complex to control the flow rate and quantity of gas fuel, and the use of ion-metering transducer to control the air supply [13,14].…”
