Performance Estimation of Fixed-Wing UAV Propulsion Systems

The evaluation of propulsion systems used in UAVs is of paramount importance to enhance the flight endurance, increase the flight control performance, and minimize the power consumption.This evaluation, however, is typically performed experimentally after the preliminary hardware design of the UAV is completed, which tends to be expensive and time-

Identifying asynchronies: Expiratory work

Mechanical ventilation is used to improve gas exchange and unload the respiratory muscles allowing for their rest and recovery, which require good synchronization between the patient and the ventilator.Spontaneous respiratory effort is generally preferred because it reduces atelectasis, improves oxygenation, and may prevent disuse diaphragm Corpora
