Transonic flutter study of a wind-tunnel model of a supercritical wing with/without winglet [PDF]

The model was a 1/6.5-size, semipan version of a wing proposed for an executive-jet-transport airplane. The model was tested with a normal wingtip, a wingtip with winglet, and a normal wingtip ballasted to simulate the winglet mass properties.

String Figuring young children's perspectives of quality in English early childhood education and care

British Educational Research Journal, EarlyView.
Abstract Quality in early childhood education and care (ECEC) is a contested concept and has generally been conceptualised by inter‐related indicators such as staff qualifications, educational environment, policy or child‐to‐staff ratios. There has been a more limited emphasis on how young children might perceive and experience quality.

Engineering habits of mind in preschool children at Scottish forest nurseries and Australian bush kinders

British Educational Research Journal, EarlyView.
Abstract Nature‐based learning environments for early childhood are expanding, as is research into their affordances and pedagogies. Engineering in these environments is not well studied. Previous work considered engineering experiences through the lens of ‘designerly play’, finding that natural materials, the space for larger creations and ...
