Aeromechanical Stability Augmentation Through Semi-Active Control
ISBN: 9783639175325 / Angielski / Miękka / 180 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Helicopter rotors have traditionally been equipped
with passive dampers for aeromechanical stability. These passive systems have fixed characteristics, and add to mechanical complexity and high maintenance cost. Furthermore, they are unable to change to compensate for an unexpected loading trends as typically encountered by a rotary wing vehicle. Semi-active control strategies are dissipative in nature, inherently stable, and require a little energy to operate. Hence, they appear to be particularly promising in addressing a number of the challenges facing active control strategies, in that... Helicopter rotors have traditionally been equipped

The Derivation of a Time-Harmonic Adjoint Method
ISBN: 9783639187700 / Angielski / Miękka / 160 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Recent years have seen a remarkable progress in aerodynamic design optimisation based on the adjoint methods to efficiently compute the sensitivities of steady-state objective functions to changes in design variables. Following this success, this book establishes an unsteady adjoint analysis whose purpose is the calculation of the linear worksum typically used in turbomachinery aeroelastic applications. The emphasis falls on the algorithmic development of the adjoint time-harmonic method, which is derived from a nonlinear flow analysis using the discrete approach. In this approach, the...

Spatio-temporal Characteristics of Spray from Liquid Jet in Crossflow
ISBN: 9783639182996 / Angielski / Miękka / 92 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. A liquid jet in a crossflow is often used to as a fuel injection method for combustion systems. Parameters such as penetration and core trajectory are used as characterization for the spray and specification of design criteria for combustor geometry. In addition to penetration and core trajectory, mapping the mass flux in space and time is an important part of modeling evaporation and global equivalence ratio throughout the combustor. Accurate prediction of these spray characteristics allows for a stable and robust combustor design. Presented are the results of measurements using Phase...

The Analysis of Flight Operational Quality Assurance (FOQA) Data
ISBN: 9783639186352 / Angielski / Miękka / 124 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The use of FOQA has become widely adopted within the last decade with the aim of increasing aviation safety. Although thousand of parameters have been available to FOQA programs, airlines have traditionally chosen a limited number for analysis; there has been no consensus on what parameters - other than the required ones - should be monitored. Therefore, several FOQA parameters that could enhance air carrier safety have not been recorded and/or analyzed. The research described in this book has no precedent in the United States. This exploratory mixed methods study began with a conference call...

Adaptive Control of Nonaffine Systems for Flight Applications
ISBN: 9783639180008 / Angielski / Miękka / 76 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Due to the nonlinear-in-control nature of the dynamical system in aggressive flight maneuvers, well-known dynamic inversion methods cannot be applied to determine the explicit form of the control law. Additionally, the aerodynamic uncertainties, typical for such regimes, are poorly modeled, and therefore there is a great need for adaptive control methods to compensate for dynamic instabilities. In this book, an adaptive control design method for both short-period and lateral/directional control of a fighter aircraft is presented. The approach uses a specialized set of radial basis function...

ISBN: 9783639190847 / Angielski / Miękka / 124 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Low Reynolds number aerodynamics is characteristic of the flight of many natural and man-made flyers. With the advent of the micro air vehicles (MAVs), vehicles with a maximal dimension of 15 cm or less and a flight speed of 10 m/s, the aerospace engineering community started to conduct studies about the aerodynamic characteristics of the flight of birds, bats and insects. The primary focus of this book is a computational study of the aerodynamic characteristics of a dragonfly aerofoil. From past studies dragonfly wings, compared with a flat plate or a conventional smooth airfoil, highlighted...

The integration of UAVs into controlled airspace
ISBN: 9783639200812 / Angielski / Miękka / 124 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Over the last decades, the importance of UAVs in general aviation has grown tremendously. Although at first, UAVs were only used in wartime, the last years they have proven to be capable of playing an important role in civil applications as well. Up till now however, there are no clear regulations on how to integrate these UAVs into the airspace and make them coexist with manned aircraft. This book wants to help incorporating UAVs into controlled airspace by discussing the main anti- collision systems and the attached regulations. In a first part, a general discussion is held about...

Development of a Simulator for the Testing of Avionics Displays
ISBN: 9783639204773 / Angielski / Miękka / 128 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Avionics displays play an important role in the safe operation of an airplane. They present information to the pilot, on which he/she will make important decisions to control the aircraft. Accurate display of information must be guaranteed in all flight conditions. Failure of that function can lead to catastrophic situations. Intensive testing, in real or simulated flight conditions, is a way to validate the proper operation of the avionics displays. For the avionics emulator (data generator), we make use of a commercially available package called X-Plane for flight simulation. The main...

Cooperative Path Planning of Unmanned Aerial Vehicles
ISBN: 9780470741290 / Angielski / Twarda / 214 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. An invaluable addition to the literature on UAV guidance and cooperative control, Cooperative Path Planning of Unmanned Aerial Vehicles is a dedicated, practical guide to computational path planning for UAVs. One of the key issues facing future development of UAVs is path planning: it is vital that swarm UAVs/ MAVs can cooperate together in a coordinated manner, obeying a pre-planned course but able to react to their environment by communicating and cooperating. An optimized path is necessary in order to ensure a UAV completes its mission efficiently, safely, and successfully.
