Abstract:
The control of air-breathing in the bowfin, Amia calva, was investigated using experimental and analytical approaches. The air-breathing pattern of conscious, undisturbed bowfin at 22±2 °C was characterized by the responses to changes in respiratory gases in the aquatic and aerial environments. Pneumotachographic measurements of air flows during air-breathing events revealed two distinct patterns: in type I breaths exhalation was followed by inhalation; in type II air breaths, which have not been described for this species, only inhalation occurred. Under normoxic conditions both types of air

Abstract:
The method of singular perturbations is applied to the determination of the optimal range-fuel-time trajectory for an air-breathing missile. This method is shown to lead to the reduced-order "cruise-dash" model, and this model is used in the optimization study. Earlier work in this area is extended by the inclusion of two not heretofore considered limits on the dynamical system. The results of the earlier work are shown to hold throughout much of the velocity regime in which the missile operates, but operation in the very high and very low velocity ranges is shown to be sharply curtailed, wi

Abstract:
Design and development of future high speed aircraft require the use of advanced modeling tools early on in the design phase to study and analyze complex aeroelastic, thermoelastic, and aerothermal interactions. This phase, commonly referred to as the conceptual design phase, involves using first principle based analytical models to obtain a practical starting point for the preliminary and detailed design phases. These analytical models are expected to, firstly, capture the effect of complex interactions between various subsystems using basic physics, and secondly, minimize computational costs

An investigation was carried out to study the process of rotating stall inception in a low hub-tip ratio fan. Such fans are expected, based on an elementary analysis, to stall from the root.

The effects of streamtube contraction were first studied and this was followed by an experimental investigation on an isolated rotor, with successive build modifications to increase the likelihood of rotating stall inception occurring at the root.

Polymer electrolyte fuel cells (PEMFC) convert chemical energy into electrical energy with high energy efficiency. Air-breathing PEMFC is a type of fuel cell suited for portable application owing to certain properties such as light weight and low operating temperature.

Temperature directly influences the water management and the rate of oxygen reduction, whereas pressure, due to clamping of the cell, acts as one of the main dominant characters in the performance of the cell in the case of air-breathin

Air intake related aerodynamic aspects of an air breathing cruise missile are analyzed.

The pre entry force can be computed relatively easily, while the cowl force depends strongly upon actual intake geometry and no general method exists. An approximate cowl force is computed based on
