N2 - The impact of cirrus cloud on Laminar Flow Control (LFC) has been reviewed. Analysis of previously published work allowed for reducing the problem to one of how particles, dispersed in the free stream, can deteriorate laminar flow in general. Motivation for reinvestigating the matter was found in the existing discrepancy between the limited available information and the need for a more detailed understanding of the subject, which is required for taking full advantage of laminar flow technologies and their secure operation. Furthermore, there exists renewed interest in laminar flow applications by both the manufacturers and the airlines in order to cope with promised efficiencies and increasing fuel costs. Preliminary experimental work has reproduced the effect in a laboratory environment and yielded results that compare well to earlier theoretical analysis. The double pitot technique has been proven to provide meaningful answers. For future work, the use of modern flow visualization techniques is deemed to be a necessary requirement for widening the available picture and effectively understanding the elementary phenomena. Within a supporting Computational Fluid Dynamics (CFD) study, good agreement has been found with the published analytical criteria regarding the particle trajectories and with published water droplet impingement data.
