Feasibility Study of Rotorcraft Fire Fighting for High-Rise Buildings
Publisher: American Society of Civil Engineers
Abstract: Fire risk in high-rise buildings is of special concern to the fire community, since it is crucial but still technically extremely challenging to significantly improve the current fire fighting capabilities when a calamity ...
Trajectory Optimization for DDE Models of Supercavitating Underwater Vehicles
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this study we first develop a flight mechanics model for supercavitating vehicles, which is formulated to account for the dependence of the cavity shape from the past history of the system. ...
Scaling of Constraints and Augmented Lagrangian Formulations in Multibody Dynamics Simulations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper addresses practical issues associated with the numerical enforcement of constraints in flexible multibody systems, which are characterized by index-3 differential algebraic equations ...
Parameter Estimation of Multibody Models of Unstable Systems From Experimental Data, With Application to Rotorcraft Vehicles
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, we consider the problem of estimating the parameters in mathematical models of complex systems from experimental observations; the methods and procedures that we develop are ...
Rotorcraft Trajectory Optimization with Realizability Considerations
Publisher: American Society of Civil Engineers
Abstract: This paper considers the problem of computing optimal trajectories for rotorcraft systems. The vehicle is described through a flight mechanics model, and the optimal control problem is solved by discretizing the vehicle ...
Global Solution of Optimization Problems in Rotorcraft Flight Mechanics
Publisher: American Society of Civil Engineers
Abstract: In this paper, the authors present a procedure for the global solution by the use of evolutionary algorithms of trajectory optimization and parameter estimation problems for rotorcraft vehicles. The proposed approach makes ...
