    摘要： The present invention provides a to method for reinforcing a wind turbine blade, such as a root end. The root end comprises a first and a second bushing for attaching the wind turbine blade to a wind turbine hub, the bushings being located between an inner sidewall of the root end and an outer sidewall of the root end, the bushings being separated by retaining material, the method comprising forming a first injection channel in the retaining material; forming a first pressure release channel in the first retaining material, wherein the first pressure release channel is formed to be in fluid communication with the first injection channel in a region between the inner sidewall and the outer sidewall; and injecting adhesive material into the first injection channel at least until adhesive material enters the formed first pressure release channel. The invention also provides a wind turbine blade having a root end that has been reinforced using such a method. Further aspects are provided.

    摘要： An airborne ultrasonic testing system includes two sets of ultrasound transmitters and receivers, an ultrasound frequency generator, a computer analyzer, and a controller. The ultrasound transmitters and opposing receivers are fixedly mounted at oblique angles from a support. A seal-receiving slot is defined between the transmitters and receivers, and is sized to receive a sealed edge portion of a container to be tested. The ultrasound transmitters preferably emit respective ultrasound streams that encounter a top surface of a sealed edge portion of the container at an angle between approximately 0-45 degrees, and most preferably, approximately 45 degrees. The angle of ultrasound emission of the first transmitter may be inverse of the angle of emission of the second transmitter. The signal response of each pair of receivers can be processed individually or combined to produce a summary test result of the two measurements that eliminates systematic variation associated with material variation.
