VetterAircraft Lifting Bags –Recovery sets for the A 380The two differing recovery systems for the AirbusA 380 are especially characterized by the followingfeatures:Alternatively, these two sets can be supplied in thefield-proven design:– 1.0 bar (14.5 psi) technology– this achieves increased stability– this makes it suitable as an upgrade for the existingsystems– a coupling system easy to use– equipped with stable claw couplings– individual system for contour matching– with corresponding contour matching system– with an operating pressure of 0.5 bar (7.25 psi)– 2 new ALB (Type 30/380 and Type 60/400)ALB 30/3802ALB 60/400

Aircraft Lifting Bags1.0 bar/14.5 psiVetterAircraft Lifting Bags1.0 bar/14.5 psiAircraft lifting bags are characterized by their sturdiness,strength, exceptional side stability and stability under load.In parallel to the existing series with an operating pressureof 0.5 bar/7.25 psi, the product program was extended toa second construction series (having an operating pressureof 1.0 bar/14.5 psi).As opposed to the 0.5 bar/7.25 psi series, the side stabilityof the 1.0 bar/14.5 psi series is increased by 40%.In addition to the operating pressure and the increasedside stability, another essential distinctive feature is thecoupling system.With the 1.0 bar/14.5 psi series, the ALB, hoses andcontrollers are fitted with rapid snap-in couplings, resp.nipples. This enables time-saving and easy inter-couplingof the individual elements.Sizes and lifting heights are identical for both series,however the nominal lifting power for the 1.0 bar/14.5 psiseries is double that of the other series.This series also enables the divided top chambers to matchto the aircraft contours.Coupling system 0.5 bar / 7.25 psiCoupling system 1.0 bar / 14.5 psiAdvantagesSafety– 40% higher stability against transverse forces– each ALB chamber has an integrated safety valve– easy and quickly useable coupling system– 2.5 times the bursting pressure to the operating pressure– optimum matching to the aircraft contours usingdivided contact chambers– protection bushes on all connection nipples– supplied as a fixed complete bag or as individualchamber– highly tear-proof polyamide fabric– space weave fabric avoids bulging of the top andbottom plates– test pressure of 1.5 bar (21.75 psi)– resistive against oil and ozone– can be repaired– long life duration of approximately 15 - 20 years5

VetterAircraft Lifting Bags5/120 NG 0.5 bar/7.25 psiThis compact set enables material protective recovery ofaircraft when normal recovery equipment cannot beused. Their prime purpose is to produce free spaceunderneath the aircraft so that suitable devices can beused for recovery operations.Due to its lifting power of 5.6 t and a lifting height of120 cm (47.2 inch), this set is suitable for use on lightaircraft as well as on business aircraft and Lear jets. Thenumber of lifting bag sets and the type of equipment ismainly dependent on the type of aircraft to be recoveredand its position.Hose coupling/nippleIn the transport and storage box there is an integrated6-section controller with dead man switching as well asthe corresponding inflation hoses and an air supply hosein addition to the ALB.An essential advantage of the compact set is the ingeniouslyeasy-to-use coupling system.AdvantagesSafety– ready-to-use unit in the transport and storage box– controller with dead man switching– each chamber can be individually controlled andchecked– 4 times the bursting pressure to the operating pressure– ingeniously easy-to-use coupling system– 1.3 times the test pressure to the operating pressure– space weave of the fabric avoids bulging of top andbottom plates– exceptionally sturdy and abrasion-proof fabric coating– can be repaired– life duration approximately 15 - 20 years8– protection bushes on all connection nipples– resistive against oil and ozone

VetterAircraft Lifting Bags0.5 bar/7.25 psiThe pneumatic aircraft lifting bags are designed so thattheir surfaces softly position to the contours of theaircraft and the pressure is optimally distributed over it.With a maximum insertion height of 25 cm (10 inch) anda bag area of up to 14 m2 the ALB are ideally suited tolift aircraft evenly up to 4 m/13 ft. (without any supportfrom underneath).ALB 30/305The strong lifting power of up to 60 tons per bag and theenormous side stability, due to the space weave fabrichaving thousands of individual threads per square metre,ensure safe recovery.Some of the essential characteristics of the modified ALBare a size matching related to the positioning area as wellas the addition of 3 new sizes (refer to Technical Data).The ALB are manufactured in 8 standard sizes.AdvantagesSafety– each chamber can be individually controlled andchecked– automatic pressure monitoring of the contour chambers– extensive range of accessories– divided top chambers enable matching to the contoursof the aircraft– 4 times the bursting pressure to the operating pressure– supplied as a fixed connected complete bag or asindividual chamber– 1.3 times the test pressure to the operating pressure– space weave of the fabric avoids bulging of top andbottom plates– resistive against oil and ozone– can be repaired– life duration approximately 15 - 20 years10– all controllers are fitted with safety valves andmanometers– protection bushes on all connection couplings– exceptionally sturdy and abrasion-proof fabric coating

DESIGN AND DELIVERY PACKAGEThe ALB are basically designed for both series,0.5 bar/7.25 psi and 1.0 bar/14.5 psi, as follows:The individual chambers are arranged numericallyexactly the same as the related controllers, this ensuresthat there is clear allocation between controller andALB chamber.The divided top chambers, which are in direct contactwith the aircraft contour, are marked alphabetically.The corresponding manometer and lever on the controllerresponsible for the control of these chambers are alsomarked alphabetically.The delivery package of one set of ALB contains:1 Aircraft Lifting Bag1 Padded plate, 10 mm / 0.4 inch1 Packing bag1 Set of repair material1 Transport and storage boxThe only exception is the set ALB 5/120. This is suppliedas a compact package and includes controller, inflationhoses and air supply hose.Fitting controller without contour chamber controlWith controllers one basically differentiates between afitting design and a dead man switching design. Thestandard controllers are supplied as 5 section, 10 sectionor 17 section devices. There are two types of 10 sectionand 17 section controllers: the controller with contourchamber regulation and those without this facility.The controllers with contour chamber regulation have anadjustable pressure regulator integrated for 0.1 to 0.5 bar(1.45 to 7.25 psi) enabling constant pressure in the divided contact chambers. There are either 2 or 3 contactchambers depending on the size of the bag.In order to inflate the larger bags two controllers areconnected together via a connection hose to form oneunit owing to the number of chambers involved.For this, there is a controller without contour chamberregulation for the lower chambers and a controllerwith regulation for the upper chambers.Aircraft Lifting Bags0.5 bar/7.25 psiCONTROLLERSDead man controller with contour chamber controlFitting controllerDead man controller– supplied with 5 sections, 10 sections or 17 sections– available as 10 section controller and 17 sectioncontroller– 10 section controller and 17 section controller withor without contour chamber control– can be supplied with or without contour chamber control– low in weight– high quality glass-fibre reinforced housing– sturdy and little maintenance needed– dead man operation (automatic zero adjustment)– other sizes on request– various colours for the control levers thus achievingbetter distinction between contact chamber control (red)and control of the other chambers (black)– short inflation times– low in weight13

Contour matchingAircraft Lifting BagVetterContour matchingContour matching can be carried out using two differentmethods:– contour matching using contact chambers of theaircraft lifting bag– contour matching using vacuum chambersCONTOUR MATCHING USING THE CONTACTCHAMBERSThe transverse and longitudinally arranged bag chambersenable optimum matching to the positioning surfaces,especially if the aircraft is positioned at an angle.The foam rubber padded plate (10 mm/0.4 inch) is usedas a protection against sharp-edged parts. A padded plate(30 mm/1.2 inch) can be additionally ordered.CONTOUR MATCHING USING VACUUMCHAMBERSThe increasing number of new aircraft fuselage andwing shapes make contour matching imperative in thefield of aircraft recovery using pneumatic lifting bags.It was for this reason that Vetter GmbH further developeda field-proven recovery system in cooperation with theauthorities at Frankfurt Airport which offers the following advantages:– low pressure point loading on sensitive aircraft parts– meets the specifications of the aircraft manufacturers– high degree of stability– high safety standard– individual contour matching16ALB 60/400

Stabilization is made in a number of steps:Step 1Step 2In the first step, a pneumatic aircraft lifting bag ispositioned under the wings of the aircraft to be recovered.In the second step, vacuum bags are positioned on thelifting bag facing the fuselage.These vacuum bags are similar to vacuum mattressesused by rescue services and exactly match to the contours.Contour matchingWhen a vacuum is then produced in the bags theywill shape themselves to the contours and stabilize theaircraft.17Vacuum bags before contour matchingVacuum bags aftercontour matching
