Book excerpt: Propulsion systems based on the pulsed detonation cycle offer the potential to provide increased performance while simultaneously reducing engine weight, cost, and complexity, relative to conventional propulsion systems currently in service. The increased performance potential is due to the high thermodynamic efficiency of detonation combustion. The near constant volume heat addition process of the detonation cycle, along with the lack of a compression cycle lend to the high efficiency and specific impulse, simplicity, and low-cost of pulse detonation propulsion systems. Pulse detonation Engines (PDEs) have the potential for operation at speeds ranging from static to high-supersonic (M

Book excerpt: Detonation waves are self-sustained supersonic combustion waves [1]. These waves are led by a shock, which compresses the fresh reactive media to a much higher temperature and pressure for rapid reaction [1]. The tremendous reaction heat release occurring behind the shock in return energizes the propagation process. As such, this closely coupled shock-reaction complex self-sustains. Detonation waves can be sustained in a variety of energetic media including reactive gases. The large overpressures generated behind gaseous detonations make them attractive and useful for developing propulsion systems [2], such as rotating detonation engines (RDEs) [3, 4] and pulse detonation engines (PDEs) [5, 6]. These applications require reliable control of the accurate ignition and stable propagation of a detonation wave. Likewise, for safety applications [7,8], it is also desirable to have the predictability for the eventual initiation of a detonation wave and for its propagation limits when different mitigation strategies are used [9]. Therefore, realizing all these practical purposes requires predictive capability of detonation behavior. Detonations in gases usually propagate with lateral strain. For example, in confined geometries of small size, such as narrow channels or tubes, detonations are subject to significant losses induced by boundary layers, which act as a mass sink and result in flow divergence in reaction zones, thereby giving rise to lateral strain impacting the detonation propagation [10]; while in geometries of varying cross-section areas or curved channels, as typically seen in PDE pre-detonator tubes and RDE combustors, detonations are curved with the flow also diverging after passing the leading front [11-13]. These lateral strain rates are generally known to decrease the detonation speed and its propagation limit [10, 11, 13-17]. Thus, in order to achieve the practical purposes of either utilizing or avoiding detonations, the effect of such lateral strain rat

Available in PDF, EPUB and Kindle. Book excerpt: The report describes quantitatively the performance characteristics of four models of the detonation engines. The four models were developed and tested using a nitrogen tetroxide/hydrazine hypergolic propellant combination. The report includes a comparative systems analysis which points out the potential areas of application for the detonation engine. The analysis indicates that the detonation engine is best suited to low duty cycle applications which require very small impulse bits, such as tight limit cycle control of a satellite, or control of a spinning satellite by spin axis precession.

Available in PDF, EPUB and Kindle. Book excerpt: A series of related analytical and experimental studies are focused on utilizing detonations for emerging propulsion and power generation devices. An understanding of the physical and thermodynamic processes for this unsteady thermodynamic cycle has taken over 100 years to develop. An overview of the thermodynamic processes and development history is provided. Thermodynamic cycle analysis of detonation-based systems has often been studied using surrogate models. A real gas model is used for a thermal e ciency prediction of a detonation wave based on the work and heat speci ed by process path diagrams and a control volume analysis. A combined rst and second law analysis aids in understanding performance trends for di erent initial conditions. A cycle analysis model for an airbreathing, rotating detonation wave engine (RDE) is presented. The engine consists of a steady inlet system with an isolator which delivers air into an annular combustor. A detonation wave continuously rotates around the combustor with side relief as the ow expands towards the nozzle. Air and fuel enter the combustor when the rarefaction wave pressure behind the detonation front drops to the inlet supply pressure. To create a stable RDE, the inlet pressure is matched in a convergence process with the average combustor pressure by increasing the annulus channel width with respect to the isolator channel. Performance of this engine is considered using several parametric studies. RDEs require a fuel injection system that can cycle beyond the limits of mechanical valves. Fuel injectors composed of an ori ce connected to a small plenum cavity were mounted on a detonation tube. These fuel injectors, termed uidic valves, utilize their geometry and a supply pressure to deliver fuel and contain no moving parts. Their behavior is characterized in order to determine their feasibility for integration with high-frequency RDEs. Parametric studies have been conducted with the type of fuel injected, the ori ce diameter, and the plenum cavity pressure. Results indicate that the detonation wave pressure temporarily interrupts the uidic valve supply, but the wave products can be quickly expelled by the fresh fuel supply to allow for refueling. The interruption time of the valve scales with injection and detonation wave pressure ratios as well as a characteristic time. The feasibility of using a detonation wave as a source for producing power in conjunction with a linear generator is considered. Such a facility can be constructed by placing a piston{spring system at the end of a pulsed detonation engine (PDE). Once the detonation wave re ects o the piston, oscillations of the system drive the linear generator. An experimental facility was developed to explore the interaction of a gaseous detonation wave with the piston. Experimental results were then used to develop a model for the interaction. Governing equations for two engine designs are developed and trends are established to indicate a feasible design space for future development.

Available in PDF, EPUB and Kindle. Book excerpt: The Penn State-led MURI effort on Pulse Detonation Engine (PDE) Research is detailed in this report. The multidisciplinary research effort brought together a team of leading researchers in the areas of the initiation and propagation of detonations, liquid hydrocarbon spray detonation, combustion chemistry, injector and flow field mixing, and advanced diagnostics to study the fundamental phenomena of importance under both static and dynamic conditions representative of actual pulse detonation engine operation. The team focused its effort on conducting key experiments and analysis in the areas of (a) Fundamental Detonation Studies, (b) Injection, Mixing and Initiation, (c) Inlet-Combustor-Nozzle Performance, (d) Multi-Cycle Operation, and (e) Computer Simulation and Cycle Analysis. These study areas are five of seven topic areas that have been delineated by the Office of Naval Research (ONR) in their roadmap on pulse detonation engine research necessary for developing the technologies needed for the design of an air-breathing pulse detonation engine. The results obtained in these five study areas under this effort by researchers at Penn State, Caltech and Princeton University, coupled with the results of the effort by the sister MURI team led by the University of California at San Diego in some of the aforementioned study areas and in the remaining two study areas of (a) Diagnostics and Sensors, and (b) Dynamics and Control provide the foundation needed for the development of a PDE system. The overall success of the program stems from ONR led coordination that fostered collaboration between the two MURI research efforts and government laboratories and industry research through a series of progress workshops held at six-month intervals.
