the method by which the designers select the initial ‘baseline’ design involves the use of parametric studies. This paper describes how the aircraft initial design layout is used as the focus for further parametric studies. After a brief general introduction to the methods used, an example is presented showing how different types of parametric study are used in a case study. This example may be used...
Hypersonic Glide Vehicle (HGV) is one of the most possible ways to put the available hypersonic technology into practice. It is very important for the thermal protection system (TPS) of HGV to predict the heating on the surface fleetly and accurately. In this paper, one quick-predict method for a typical HGV with conically derived waverider construction and skip-glide trajectory was investigated firstly...
Traditional portable maintenance aid (PMA) needs a significant amount of storage memory for storing electronic manual and maintenance information, so it has characters of big size and high power consumption. In order to overcome these shortcomings, a wireless portable maintenance aid (W-PMA) is designed in this paper, based on wireless network and embedded system. W-PMA integrates functions as interactive...
By analyzing the principle of the angle error of the MLS receiver, an error research method based on the equivalent replacement of the scanning beaming main lobe is presented. Through the equivalent Gaussian replacement of the beam main-lobe of "From" and "To" pulse, the error formula in the presence of several multi-path components is derived. The method is used to calculate the...
