This paper provides an overview oabout the design of the LinkMAV rotary wing autonomous Micro Aerial Vehicle. The paper describes the flying platform, the main problems related to aerodynamics and propulsion, the onboard avionics and the flight control system, including the autonomous navigation algorithms. We also describe the sensor chosen for the MAV05 competition, held in Garmisch Partenkir...

A simulation framework for vehicle aerodynamics using up to 10 billion fully-unstructured numerical elements has been developed on the world fastest class supercomputer called the “K computer”. The K computer is installed at the RIKEN Advanced Institute for Computational Science in Kobe, Japan, consisting of over 80,000 processors of a distributed memory architecture with its peak performance o...

The Multi-Mission Earth Entry Vehicle project is developing an integrated tool called “Multi Mission System Analysis for Planetary Entry Descent and Landing” that will provide key technology solutions including mass sizing, aerodynamics, aerothermodynamics, and thermal and structural analysis for any given sample return mission. Thermal soak analysis and temperature predictions of various compo...

The problem of modeling and controlling vehicle longitudinal motion is addressed for front wheel propelled vehicles. The chassis dynamics are modeled using relevant fundamental laws taking into account aerodynamic effects and road slop variation. The longitudinal slip, resulting from tire deformation, is captured through Kiencke‟s model. A highly nonlinear model is thus obtained and based upon ...

The cause of drag force vehicle accounts high fuel losses. Fuel consumption is adversely affected due to aerodynamic forces, which specially the force. Vehicles that are moving in certain arrangement allows for a significant decrease at highway speeds by reducing on vehicles. In this paper, effect resistance was numerically investigated. models were arranged back-to-back with difference distanc...

The use of flexible mode control implemented through the use of aerodynamic surfaces is examined for two case vehicles: a magnetically levitated vehicle and a towed aerodynamic vehicle. A summary of the aerodynamics of trapezdoial and annular wings is presented first, followed by an analysis of the modal characteristics of the test vehicles. LQR design methods using the flexible mode and its ra...

A summary of the propulsion system modeling under NASA’s High Speed Project (HSP) AeroPropulsoServoElasticity (APSE) task is provided with a focus on the propulsion system for the lowboom supersonic configuration developed by Lockheed Martin and referred to as the N+2 configuration. This summary includes details on the effort to date to develop computational models for the various propulsion sy...
