SYSTEM OF BALLONETS FOR LIGHTER-THAN-AIR FLYING VEHICLES

摘要

lighter-than-air flying vehicles. SUBSTANCE: proposed system includes many ballonets located inside envelope of flying vehicle. Each ballonet has flexible sheet connected with section of wall 44 of envelope over periphery. Air inflating system 45 is connected with each ballonet; this system includes section of wall 44 of envelope forming ballonet with many through holes 54. Air duct 60 connected with wall inlet hole 64; air duct closes holes 54 and ensures diffusion of compressed air fed to ballonet. Besides that, system includes at least one fan 46 whose inlet end 50 is communicated with surrounding atmosphere and outlet end is connected with intake hole 64 of air duct 60 for feeding the compressed air to cavity of ballonet. Check valve 52 fitted at outlet end 51 of fan 46 is used to prevent air from escaping from air duct through outlet end of fan. Provision is also made for air-bleeding system 70 discharging air from ballonet to atmosphere. EFFECT: increased rate of flatting and deflecting the ballonets. 6 cl, 5 dwg
