Accelerating Full Scale Fatigue Testing

Proceedings of the Vertical Flight Society 79th Annual Forum, 2023
This paper will discuss the use of Model Predictive Control (MPC) to increase the speed and accuracy of airframe fatigue testing. This will save time and cost while providing a very high fidelity test that will greatly reduce future fleet problems.

Full-scale aircraft tire pressure tests

2009
This paper describes an outdoor full-scale test planned to improve experimental and theoretical knowledge related to the effects of aircraft internal tire inflation pressure on the behavior and damage of flexible pavement. Since modern aircraft can have tire pressures greater than 15 bar, the tests will focus on pressures from 15 bar to 17.5 bar.

Rockfall Full Scale Field Tests

2013
The phenomenon of rockfall along slopes is an environmental risk that frequently occurs in mountainous regions. In this phenomenon are directly involved infrastructures (railways, ordinary roads or highway) but also residential areas as well as individual structures are also interested in prevention and defense.

Full-scale collision tests

Safety Science, 1995
The Association for Structural Improvement of Shipbuilding Industry (ASIS) and the Netherlands Foundation for the Coordination of Maritime Research (CMO) jointly conducted a series of collision tests on full-scale ships in December 1991. Four different tests were carried out using two fully instrumented tankers for inland waterway navigation.

Fatigue Test on a Full Scale Panel

Key Engineering Materials, 2006
Fatigue test on a full scale panel with complex loading and geometry has been carried out by using a tri-axial test machine located in the laboratory of the University of Naples. The aeronautical test panel was designed and manufactured by Alenia. The demonstrator is made up of two parts which are linked by a transversal joint that is parallel to the ...

Vibration testing of full-scale structures

Nuclear Engineering and Design, 1973
Abstract Vibration testing of nuclear reactor plant systems is discussed as a part of the determination of the response of such systems to earthquakes. The methods of ambient, harmonic excitation, and impulse testing are compared. Harmonic excitation tests provide a method of obtaining the complete dynamic characteristics of a system and of ...

Full-Scale 3D Wall Bracing Tests

Structures Congress 2008, 2008
Beginning in early 2006, the APA Research Center expanded to include the capability of testing full-scale three-dimensional houses. This paper summarizes results of wall bracing racking tests from a full-scale 25 x 37.5 x 9-ft-tall three-dimensional wood frame house.
