In this paper we present algorithms and experiments for multi-scale assembly of complex structures by multi-robot teams. We also focus on tasks where successful completion requires multiple types of assembly operations with a range of precision requirements. We develop a hierarchical planning approach to multi-scale perception in support of multi-scale manipulation, in which the resolution of t...

The increasing development in aerial vehicles shows a wide range of configurations for different requirements. Many them combine conventional configurations’ features to take advantage their qualities, such as performing cruise flight an airplane and hovering like helicopter. Thereby, this study analyzes the modeling control pair fixed-wing airplanes joined together form larger rotor that incor...

Nomenclature (contlnued) The paper discusses the development and testing of a real-time Takeoff Performance M Pitching moment (ft_lb) Monitoring System. The algorithm is madeup of two MACH Mach number segments: a pretakeoff segment and a real_time p Roll Rate (rad/sec) segment, q Pitch Rate (rad/sec) One_time inputs of ambient conditions and r Yaw Rate (rad/sec) airplane configuration informati...

SOUND AND VIBRATION/NOVEMBER 2002 A brief overview is given of transport airplane ground vibration testing (GVT) at Boeing Commercial Airplane Group. A GVT is a modal test conducted for the purpose of validating and improving a structural dynamic model of the airplane. A “small signal” model is quickly and conveniently identified from multi-input burst random excitation. Sine excitation is used...

The flat spin of a fixed-wing airplane is usually considered to be dangerous, and should avoided by all means. However, an in descends almost vertically relatively slowly. It can used as means vertical landing, especially for small unmanned aerial vehicle. Controlling the impact speed ground touchdown position necessary realize application flat-spin landing. A large pitch-up moment generated co...

There is a tight connection between the Pre-Design (development of requirements for designed airplane) and Conceptual Design stages while creating new aircraft. Taking this into account would result in design more optimal aircraft that have appropriate advantage during operation. Previously when ability to take such interconnections was lacking designers were forced allocate certain reserves pr...
