When firing my pulse jet I tried various approaches at increasing its' performance without significantly increasing its' weight. When (while holding a piece of larger diameter pipe with channel locks) introducing a larger diameter than the jet diameter pipe into and partially allowing the larger dia, pipe to find its' natural location I discovered (felt) something that was described as 'the Coanda Effect' . A database search reveals disagreements among 'people in the know' regarding the mechanism for describing 'LIFT'.Is there a definitive answer??
