Abstract
This is a preliminary report pertaining to the development of a shape memory alloy based smart repair device. This device is proposed to be used to bond an annular ring shaped patch in situations where it is inaccessible to repair from inside the aircraft structure, such as a wing. Once the annular ring shaped patch is bonded, then a plug can be bonded taking the support of the bonded annular ring. Hitherto,these annular rings were being bonded using conventional mechanical (screw fastener based) devices. These mechanical devices have several limitations such as uneven pressure application and cumbersome bonding procedures. In this report the development of a preliminary SMA based efficient smart repair device for a damage diameter of 75 to 80mm is discussed.
