fireproof bulkhead used in aircraft construction comprises highly porous structure formed as reticulated metallic foam or as highly porous pimple or nub structure coated with intumescent lacquer
2008Co-Authors: Berend SchokeAbstract:The fireproof bulkhead (15) comprises a highly porous structure formed as a reticulated metallic foam or as a highly porous pimple or nub structure comprising woven and laid fabric of quartz glass fiber. The intumescent lacquer is coated on the inner surface of the cell walls of the foam or the pimple or nub structure, and the intumescent coating exhibits intumescent effect at a temperature above 200, 400 or 600[deg] C. Independent claims are included for the following: (1) aircraft or spacecraft is formed as a fire barrier for a Baggage Compartment. The fireproof bulkhead is arranged to the sides of the hold (12) of aircraft or spacecraft in order to fill the cavity between the hold and fuselage (10) of the aircraft or spacecraft; and (2) method for producing fireproof bulkhead involves performing coating by spraying or dip coating the highly porous structure with an intumescent material.

Always watchful of your arrival and departure, Baggage handlers wait to serve you how Baggage handling in an airport can entail in biomechanical risks
Quito: USFQ 2015., 2015Co-Authors: Gachet Carrillo, Stephano XavierAbstract:Baggage handling is a high risk job that presents awkward postures, overexertion and repetition in their activities. Ergonomic studies have used biomechanical and psychophysical approaches to evaluate the level of risk of MSDs in Baggage handlers. Most of the studies target the activities in the aircraft Baggage Compartment. The objective of this study was to determine the risk level of MSDs in Baggage handlers of the Quito airport through the application of biomechanical risk factors identification tools, in order to propose control strategies that could reduce the mentioned risk. The study analyzed the manual handling activities performed in the Baggage tunnel. Four activities were identified and 95 Baggage handlers of the Quito airport were evaluated using the RULA. Also, the Maximum Acceptable Weight of Lift (MAWL) was applied to determine the lift capacity of Baggage handlers in the Quito airport. The RULA analysis determined a total score of 7, Action Level 4, for each of the activities evaluated, for the 100% of the Baggage handlers. The activities performed by TAME and ANDES were found to be equal, but their lifting frequencies were not. On the other hand, the MAWL for the population of male Baggage handlers in the Quito airport was determined to be 7 kg, which compared to the actual average weight of the bags lifted is much lower. Therefore, this study determined that Baggage handling activities performed in the Baggage tunnel present a high risk of developing an upper MSD, and work conditions should be changed immediately. Finally, administrative and engineering controls were proposed in order to reduce the biomechanical risk level that result from Baggage handling activities

Product development of an airing hook
Högskolan i Borås Akademin för textil teknik och ekonomi, 2020Co-Authors: Edvardsson Emma, Hedlund Andreas, Larsson SimonAbstract:Rapporten innehåller en produktutvecklingsprocess av en justerbar friskluftskrok. En friskluftskrok har i uppgift att fästas i bagageluckans låsanordning på en personbil för att möjliggöra för vädring, då kroken håller luckan på glänt. Syfte med arbetet är att med hjälp utav det uppsamlade kunskaper från tidigare studier utveckla och designa en användbar produkt. Därmed utöka gruppens kunskap och erfarenhet av arbete inom produktutveckling. Detta åstadkoms genom framtagning av lösningar som tillfredsställer målgruppens behov och önskemål. Dessa konkretiseras med hjälp av en marknadsundersökning. För att åstadkomma önskat resultat kommer välkända produktutvecklingsmetoder att användas för att effektivt utveckla produkten. Olika koncept för det olika delar av friskluftskroken jämförs med varandra, sedan väljs ett fåtal koncept för vidare prototyputveckling. Dessa prototyper tillverkas med en 3D-skrivare och testas på olika bilar. Resultaten från dessa tester används sedan för vidare utveckling av prototyperna. I resultatet redovisas den färdigställda produkten genom att beskriva dess utseende, hur den skall tillverkas och dess egenskaper.This report describes the product development process of an adjustable fresh air hook. The purpose of a fresh air hook is to be attached to the car’s trunk lid and its locking device to allow for air circulation inside the Baggage Compartment thus decreasing the temperature, as the hook keeps the door open. The purpose of the work is to develop and design a usable product with the help of the knowledge gathered from our studies. This will increase the group's knowledge and experience of work in product development. This is achieved through the development of solutions that satisfy the needs and wishes of the target group. These are concretized by means of a market survey. To achieve the desired result, well-known product development methods will be used to effectively develop the product. Different concepts for the different parts of the fresh air hook are compared with each other, then a few concepts are chosen for further prototype development. These prototypes are made with a 3D-printer and tested on different cars. The results of these tests are then used for further development of the prototypes. In the result, a report of the finished product is presented by describing its appearance, how it is manufactured and its properties

Blast response of a pressurized aircraft fuselage measured using high-speed image correlation
2011Co-Authors: Backman D., Gould R.Abstract:As part of a project examining the blast response of a pressurized aircraft fuselage, high-speed digital image correlation was used to measure the change in surface strain and out-of-plane displacement during an explosive event. Two explosive charges were used for this test, one located in the aft cargo Compartment and one located in the forward cargo Compartment. Digital image correlation was used to monitor the charge in the aft Compartment with the second charge in the forward Compartment being detonated 100 ms after the first. Digital image correlation was able to monitor the change in out-of-plane displacement as a result of the high-temperature gas generated during the explosion. Strain measurements made during the explosion were used to calculate the Von Mises stresses and confirmed that the aluminum skin did not plastically deform. The second explosion in the forward Baggage Compartment did result in fracture of the fuselage skin and post-test analysis of the fracture surfaces showed that tensile stresses in the rivets likely led to failure. \ua9 2012, National Research Council Canada.Peer reviewed: YesNRC publication: Ye
