According to Wiki, some of the German Stuka in WWII had "a wind-powered siren under its nose (later mounted to the front upper section of each fixed landing gear strut) that wailed during dives to frighten its victims. These were named Jericho-Trompeten, or "Trumpets of Jericho", by Junkers and were a form of psychological warfare."
And on the other website: "In adition to it's weaponry the Stuka sometimes were equipped with wind-powered sirens on the wheel covers that made a terrible and frightening noice during the dive. Nicknamed "Trumpets of Jericho" - the siren was probably the brainchild of Udet. The bombs were also sometimes equpied with whistles. The siren and the whistles worked as an psychological weapon and imposed fear upon the enemy soldiers under attack."
Has anyone seen or heard such device on a surviving or replica of the planes?
