Abstract
Wind tunnel testing of an aircraft anti-armor bomb (PTAB) is performed to determine its aerodynamic coefficients at subsonic and transonic flow regimes. In the same regimes, the fuze mechanism arming time is tested, directly depending on the local flow field around the anti-armor bomb. The objective of this investigation is to define a reliable method of determining the fuze mechanism arming time. A verification of the same characteristics of the anti-armor bomb in real flight conditions will be taken into consideration to approve the method after wind tunnel testing.
Highlights
Growing efficiency of air defense systems imposes on attacking aircraft to perform attacks at low altitude and to leave the target area as fast as possible

Summary
Model protivoklopne avio-bombe za aerotunelska ispitivanja je geometrijski i aerodinamički sličan originalu, u razmeri 1:1. Protivoklopna avio-bomba ima cilindrično telo sa ravnom čeonom površinom. Po obodu svog zadnjeg dela avio-bomba ima šest sklapajućih, simetrično raspoređenih krilaca koja čine stabilizator (2), sl., a iza čega se nalazi slobodno rotirajuća vetruška (1). Slika 2 – Test model PTAB (spoljni izgled): 1 – vetruška sa centrifugalnim osiguračima, 2 – stabilizator sa sklapajućim krilcima, 3 – telo bombe. 2 – Тестовая модель ПТАБ (внешний вид): 1 – крыльчатка с центребрежными предохранителями, 2 – стабилизатор со складывающимися лопастями, корпус бомбы Figure 2 – PTAB Test Model (exterior sideview): 1 – arming vane with centrifugal safety pins, 2 – stabilizer tail unit with folding fins, 3 – bomb body. Centrifugalni osigurači, radijalno raspoređeni po obodu vetruške, razmiču se pri graničnom broju obrtaja kada se vetruška odvaja, te na taj način omogućava uspostavljanje inicijalnog lanca, odnosno armiranje upaljača
