Aircraft and spacecraft design
Aircraft and spacecraft require light, reliable structures, and thus structure design must be improved. Although computational analysis has advanced, there are still no satisfactory design criteria for predicting buckling of thin-walled structures, and bolted and adhesive joints for composites and honeycomb sandwich panels. We are currently tackling this area of research.
Statistical prediction for material and structure strength
A- and B-basis values are used to predict whether a material is suitable for aircraft and spacecraft structures; however, there is no statistical method for evaluating the differences between calculated and experimental results, similar to buckling. Hence, we are developing statistical methods that can be applied to materials and structures.
Design and development of micro-rockets
University labs have developed and launched micro-satellites by piggybacking on large rockets. There are limited opportunities for launch using this method. We are developing micro-rockets for micro-satellites to allow cheaper, faster launches.
