The bombs are released in a sequence dependent upon the rapidity of movement of the (hand operated) lever across an arc of contacts connected to the release slips in the bomb bay.
Please, tell me how sequence of releasing depend upon the rapidity of movement? Arc on the face panel have approximatelly 20 point. After turn lever to the first (fifth, eleventh etc) point, secuence what? What parameter regulated by lever: quantity of bomb releasing or drop order? Blenheim had four point in the bomb bay – why bomb distributor had 20 point?
With best regards,
Alexander.
