DSC measurements on experimental TGDDM/DDS resin systems: The influence of variations in resin composition and catalyst content

As part of an international cooperation programme, DSC measurements were performed on 17 resin mixtures, of which the basic constituents were TGDDM and DGEBA epoxies and DDS hardener. The DDS/TGDDM and DGEBA/TGDDM ratios were systematically varied. In addition, for some of the mixtures small amounts of catalyst (0.2 and 2 weight percent) were...

The international vortex flow experiment: A test case for compressible Euler codes

As part of the joint International Vortex Flow Experiment, force and pressure measurements have been carried out on a 65 deg delta wing configuration in the transonic and supersonic wind tunnels of NLR. Out of these data three test cases were selected by the organizing committee of the GAMM WORKSHOP on the "Numerical Simulation of Compressible...

Fatigue Rated Fastener Systems: an AGARD coordinated testing programme

The report contains the description, results and conclusions of a fatigue test programme which assessed the fatigue lives of fastener systems using different joints. High load transfer single shear joints were evaluated in a core programme; secondary bending and load transfer were determined experimentally. About 750 specimens were fatigue...

A check of crack propagation prediction models against test results generated under transport aircraft flight simulation loading

The GARTEUR Group of Responsables for Structures and Materials identified the need for an evaluation of fatigue crack propagation models. This resulted in a collaborative GARTEUR activity in which 13 variations of the F-27 transport spectrum were evaluated by 7 institutes and companies using in total 13 crack propagation prediction methods and...

De invloed van CAD op research

NLR has developed an infrastructure of hardware and software for support of aerodynamic design of aircraft. Organizational and technical aspects of this development are described.

Fracture toughness and corrosion properties of the aluminium plate alloys 7010-T651 and 7150-T6E189

A comparative experimental investigation was done on the advanced plate alloys 7010-T651 from ALCAN and 7150-T6E189 from ALCOA. The mechanical properties, fracture toughness and corrosion properties were determined. The most notable finding was the excellent fracture toughness of alloy 7150-T6E189 combined with a high tensile strength. The...
