Design for Additive Manufacturing: Concepts and Considerations for the Aerospace Industry

2018-07-20
In the coming decades, the growth in AM will likely be driven by production parts that leverage this increase in design freedom to manufacture parts of higher performance and improved material utilization. Contrary to popular opinion, however, AM processes do have their constraints and limitations - not everything can be manufactured with AM, and even when it is feasible, not everything should. Design for Additive Manufacturing: Concepts and Considerations for the Aerospace Industry, edited by Dr. Dhruv Bhate, is a collection of ten seminal SAE International technical papers, which cover AM from the perspective of the appropriateness (should) and feasibility (can) of using AM for manufacturing of parts and tooling. Although AM technologies have been around for three decades, many in the industry believe that we are merely at the beginning of the revolution in the design-driven aspects of this technology.

Implementation and Testing of Magnetometer Calibration Algorithms for Autonomous Navigation Systems Application

The attitude of autonomous marine, land, air or space vehicles can be determined from the state estimation by means of mathematical tools such as Extended Kalman filter. In the process of calculation of this value, three-axis inertial and non-inertial sensors are used. From the knowledge of the orientation of the main axis, it is implemented the automatic control of the vehicle. The solid-state magnetometer is a non-inertial sensor with three axes that provides both the direction and the magnitude of the magnetic field vector which it is being submitted. However, measurements of the Earth's magnetic field vector, obtained using the three-axis magnetometer, are not accurate. In the vehicle itself, the presence of ferrous materials creates disturbances in the Earth's magnetic field, distorting the measured field.

Defying convention Rapid prototyping has the potential to play a beneficial role in unconventional autonomous airship design. By reducing model cost, build time, difficulty of construction, and maintaining acceptable surface quality and finish, designers have greater ability to analyze several configurations of airships and to change the geometry to increase stability, reduce drag, or fulfill mission requirements.
