All six types of McDonnell Douglas Helicopter Company's 300 and 500 series helicopter main rotor (M/R) blades have metal abrasion strips on their leading edges to provide additional wear protection. These abrasion strips are secondarily bonded to the M/R blade's leading edge, within strict bond-line thickness tolerances. This operation must be done with a bonding tool that can provide proper heat transfer and pressure conditions that produce an excellent metal-to-metal bond between dissimilar metals. Furthermore, on some M/R blades, the tooling used to bond these abrasion strips cannot apply too much pressure aft of the leading edge spar due to the minimal structural support in this section of the M/R blade.
