in this research, the calculation method of aerodynamic loads on an airplane in all flight situations is presented. in order to find an calculation equation for aerodynamic loads on an airplane in all flight conditions, the f-5 aircraft is selected as a prototype is divided into one hundred small parts longitudinally. therefore, the numerical solutions are taken place in different conditions of...

The six-degree equations of flight in their classic form do not provide a proper physical perception due to a number of interferences. Nor do they render visible the important role of attack angles. In this study, attempts have been made to develop a complete set of 3D acceleration equations from the equations of normal and tangential acceleration αN=vωv, αt=v ̇. For this purpose, a coordinate s...

An advanced guidance law is developed for reentry phase of a reentry vehicle. It can achieve small miss distance and desired impact attitude angle, simultanceously. To meet this requirment a guidance law based on the fuzzy logic approach is developed. It is partitioned into three stages. This guidance law does not require linearization of missile engagement model. Line-of-sight and flight path ...

How did the crisis impact financial intermediation? We address this question by studying a unique market segment, viz. foreign private debt issued in the U.S, which grew in size despite the financial crisis. Specifically foreign private (or Rule 144A) debt issued in U.S. registered over a five-fold increase compared to public (or Yankee) debt between pre-crisis and crisis periods, while at the ...

This article examines the formation and transformation of urban entrepreneurialism in the context of China’s market transition. Using the case study of Kunshan, which is ranked as one of the hundred “economically strongest county-level jurisdictions” in the country, the authors argue that two phases of urban entrepreneurialism—one from the 1990s until 2005, and another from 2005 onward—can be r...

the application of a flight simulator with six degree of freedom (6dof)) in design and analysis of rocket systems is essential. the calibration of a 6dof flight simulator is a challenging problem. this paper focuses on the calibration of a flight simulator and intends to answer the following questions: 1) does experimental design have significant impact on calibration quality? if so, which expe...

This article estimates a count-data model on the flight behaviour of Austrian holiday-makers based information from large representative quarterly survey spanning years 2014–2016. On average, number holiday flights ranges between 0.6 and 1.2 per year for residents in least populated region capital, respectively. Results estimations reveal that is highest persons with tertiary degrees, young age...
