Aircraft Collection
A, AIR & SPA ID SE CE MU REP SEU INT M AIRCRAFT COLLECTION From the Avenger torpedo bomber, a stalwart from Intrepid’s World War II service, to the A-12, the spy plane from the Cold War, this collection reflects some of the GREATEST ACHIEVEMENTS IN MILITARY AVIATION. Photo: Liam Marshall TABLE OF CONTENTS Bombers / Attack Fighters Multirole Helicopters Reconnaissance / Surveillance Trainers OV-101 Enterprise Concorde Aircraft Restoration Hangar Photo: Liam Marshall BOMBERS/ATTACK The basic mission of the aircraft carrier is to project the U.S. Navy’s military strength far beyond our shores. These warships are primarily deployed to deter aggression and protect American strategic interests. Should deterrence fail, the carrier’s bombers and attack aircraft engage in vital operations to support other forces. The collection includes the 1940-designed Grumman TBM Avenger of World War II. Also on display is the Douglas A-1 Skyraider, a true workhorse of the 1950s and ‘60s, as well as the Douglas A-4 Skyhawk and Grumman A-6 Intruder, stalwarts of the Vietnam War.

Originally built as the TBF by Grumman Aircraft Engineering Corporation, they were affectionately nicknamed “Turkeys” for their somewhat ungainly appearance.

Hendry Goyal Editor : Prof. P.Muthukumar COMPARATIVE STUDY OF TENSILE AND FLEXURAL BEHAVIOUR FOR GLASS-FIBER- REINFORCED ALUMINIUM (GLARE) LAMINATES AND ALUMINUM Asha Melba.V, Senthil Kumar.A, Vino.A # Department of CAD /CAM Engineering Sethu Institute of Technology, pulloor-626 115. [email protected] [email protected] [email protected] ABSTRACT The objective of this research article was investigated to evaluate tensile and flexural properties of Glass-fiber-Reinforced Aluminium (Glare) laminates as well as Aluminium sheets of same thickness. In addition to that the tensile and flexural strength of Glare laminates were compared with values of aluminium sheets. In this article, the aluminium based FMLs were fabricated using hand layup technique and cut as per ASTM standards. Three types of layers such as 2/1 Glare, 3/2 Glare and 5/4 Glare laminates were prepared. Computer controlled UTM machine used to determine the tensile, flexural properties and failure mode of the Glare laminates and Plain aluminium sheets with same thickness. From the test results the graphs were plotted for load vs displacement, tensile and flexural strength vs layers thickness. It shows that tensile and flexural strength of Glass-fiber-Reinforced Aluminium (Glare) laminates purely depend on the volume percentage of fibre and it exhibits improvement over the properties of aluminium sheets. Keywords: Glass-fiber-Reinforced Aluminium laminates (Glare), aluminium sheet, hand lay-up technique, tensile property and flexural property. -
