AIRCRAFT SEGMENTATION IN SAR IMAGES BASED ON IMPROVED ACTIVE SHAPE MODEL
SAR target segmentation aircraft ISOMAP
2018/4/30
In SAR image interpretation, aircrafts are the important targets arousing much attention. However, it is far from easy to segment an aircraft from the background completely and precisely in SAR images...
This article traces the evolution of long range jet transport aircraft over the 50 years since Kuechemann founded the journal Progress in Aerospace Sciences. The article is particularly focused on tra...
Sonic Boom Reduction using an Adjoint Method for Supersonic Transport Aircraft Configurations
Sonic Boom Reduction Adjoint Method Supersonic Transport Aircraft gurations
2015/7/2
The objective of this work is to develop the nec essary methods and tools to facilitate the design of low sonic boom aircraft that can fly superson ically over land with negligible environmental...
Aerodynamic shape optimization of complex aircraft configurations via an adjoint formulation
Aerodynamic shape optimization complex aircraft configurations via adjoint formulation
2015/7/1
This work describes the implementation of optimization techniques based on control theory for complex aircraft configurations. Here control theory is employed to derive the adjoint differential equati...
While aircraft environmental performance has been important since the beginnings
of commercial aviation, continuously increasing passenger traffic and a rise in public
awareness have made aircr...
The focus of the present study is to determine the feasibility of including noise and emissions
constraints in the early design of the aircraft and
mission. This paper introduces the design tool and...

2015/6/18
A set of gust
simulation studies are carried out to assess the relative importance of the various physics
involved in aircraft gust encounters and the effects of different modeling assum...
Enhanced Collaborative Optimization: Application to an Analytic Test Problem and Aircraft Design
Analytic Test Problem Aircraft Design
2015/6/18
This paper provides an introduction to a new method for distributed optimization based
on collaborative optimization, a decomposition-based method for the optimization of complex multidisciplinary de...
Aircraft Family Design Using Decomposition-based Methods
Decomposition-based Methods Family Design
2015/6/18
Two decomposition-based methods are applied to the aircraft family problem: collaborative optimization and analytical target cascading. This paper marks
the beginning of a collaborative effort ...
Framework for Aircraft Conceptual Design and Environmental Performance Studies
Conceptual Design Environmental Performance Studies
2015/6/18
A preliminary design tool that uses a multiobjective genetic algorithm
to determine optimal aircraft configurations and to estimate the sensitivities between the conflicting objectives of...
Nonplanar wings offer the possibility of reduced drag compared with planar wings of the
same span and lift. However, aircraft are not compared on the basis of drag with fixed
span and lift, making...
