    Results of a parametric study concerning low velocity impact on leading edge profiles is presented. This work is the first part of a larger program on the development of an engineering design method for impact on Glare. In this first part, experimental tests and numerical simulations on two-dimensional aluminium leading edge profiles were carried out. An extensive parametric study was done using numerical analysis. Selected configurations have been validated using impact tower testing. Impact tests were done with a solid impactor with a circular diameter on leading edges having a width of 20 mm. Profiles with three different thicknesses and three different sizes were tested. Impact velocities were in the range 1 to 8 m/s. The numerical models predicted the deformation of the leading edges accurately. Important impact parameters were identified and relations were established between impact parameters and geometrical properties of the leading edge profiles. The obtained results give important insight in the set up of simulations and experimentation and in the identification of important parameters of leading edge impact.
