Hall, Great Lakes, and Douglas all submitted designs for the competition. While Halls design, a high-wing seaplane, failed to meet BuAirs carrier suitability requirement both Great Lakes and Douglas pressed on. The Great Lakes design, the XTBG-1, was a three-place biplane that quickly proved to possess poor handling and instability during flight. The failure of the Hall and Great Lakes designs opened the way for the advancement of the Douglas XTBD-1. A low-wing monoplane, it was of all-metal construction and included power wing folding. All three of these traits were firsts for a US Navy aircraft making the XTBD-1 design somewhat revolutionary. The XTBD-1 also featured a long, low greenhouse canopy that fully enclosed the aircrafts crew of three (pilot, bombardier, radio operator/gunner). Power was initially provided by a Pratt Whitney XR-1830-60 Twin Wasp radial engine (800 hp). The XTBD-1 carried its payload externally and could deliver a Mark 13 torpedo or 1,200 lbs. of bombs to a range of 435 miles. Cruising speed varied between 100-120 mph depending on payload. Though slow, short-ranged, and under-powered by World War II standards, the aircraft marked a dramatic advance in capabilities over its biplane predecessors. For defense, the XTBD-1 mounted a single .30 cal. (later .50 cal.) machine gun in the cowling and a single rear-facing .30 cal. (later twin) machine gun. For bombing missions, the bombardier aimed through a Norden bombsight under the pilots seat. Acceptance Production First flying on April 15, 1935, Douglas quickly delivered the prototype to Naval Air Station, Anacostia for the beginning of performance trials. Extensively tested by the US Navy through the remainder of the year, the X-TBD performed well with the only requested alteration being an enlargement of the canopy to increase visibility. On February 3, 1936, BuAir placed an order for 114 TBD-1s. An additional 15 aircraft were later added to the contract. The first production aircraft was retained for testing purposes and later became the types only variant when it was fitted with floats and dubbed TBD-1A. Operational History The TBD-1 entered service in late 1937 when USS Saratogas VT-3 transitioned off TG-2s. Other US Navy torpedo squadrons also switched to the TBD-1 as aircraft became available. Though revolutionary at introduction, aircraft development in the 1930s progressed at a dramatic rate. Aware that the TBD-1 was already being eclipsed by new fighters in 1939, BuAer issued a request for proposals for the aircrafts replacement. This competition resulted in the selection of the Grumman TBF Avenger. While TBF development progressed, the TBD remained in place as the US Navys frontline torpedo bomber. In 1941, the TBD-1 officially received the nickname Devastator. With the Japanese attack on Pearl Harbor that December, the Devastator began to see combat action. Taking part in attacks on Japanese shipping in the Gilbert Islands in February 1942, TBDs from USS Enterprise had little success. This was largely due to problems associated with the Mark 13 torpedo. A delicate weapon, the Mark 13 required the pilot to drop it from no higher than 120 ft. and no faster than 150 mph making the aircraft extremely vulnerable during its attack. Once dropped, the Mark 13 had issues with running too deep or simply failing to explode on impact. For torpedo attacks, the bombardier was typically left on the carrier and the Devastator flew with a crew of two. Additional raids that spring saw TBDs attack Wake and Marcus Islands, as well as targets off New Guinea with mixed results. The highlight of the Devastators career came during the Battle of the Coral Sea when the type aided in sinking the light carrier Shoho. Subsequent attacks against the larger Japanese carriers the next day proved fruitless. The TBDs final engagement came the following month at the Battle of Midway. By this time attrition had become an issue with the US Navys TBD force and Rear Admirals Frank J. Fletcher and Raymond Spruance possessed only 41 Devastators aboard their three careers when the battle began on June 4. Locating the Japanese fleet, Spruance ordered strikes to begin immediately and dispatched 39 TBDs against the enemy. Becoming separated from their escorting fighters, the three American torpedo squadrons were the first to arrive over the Japanese. Attacking without cover, they suffered horrific losses to Japanese A6M Zero fighters and anti-aircraft fire. Though failing to score any hits, their attack pulled the Japanese combat air patrol out of position, leaving the fleet vulnerable. At 10:22 AM, American SBD Dauntless dive bombers approaching from the southwest and northeast struck the carriers Kaga, Soryu, and Akagi. In less than six minutes they reduced the Japanese ships to burning wrecks. Of the 39 TBDs sent against the Japanese, only 5 returned. In the attack, USS Hornets VT-8 lost all 15 aircraft with Ensign George Gay being the only survivor. In the wake of Midway, the US Navy withdrew its remaining TBDs and squadrons transitioned to the newly arriving Avenger. The 39 TBDs remaining in the inventory were assigned to training roles in the United States and by 1944 the type was no longer in the US Navys inventory. Often believed to have been a failure, the TBD Devastators principal fault was simply being old and obsolete. BuAir was aware of this fact and the aircrafts replacement was en route when the Devastators career ingloriously ended.

â€Å"She’s gone.† Those two words are racing through my mind. She’s gone? She’s gone? What do you mean? With every crippling second, the anxiety is taking over my body.

My client, (full time DJ) Mr. I. C. We will write a custom essay sample on ICT Database or any similar topic only for you Order Now H. Cheezeburger has just been employed by Avenue Q, a newly opened club in the west end. He is currently having problems organising his very vast and varied, music collection. He currently organizes his collection manually using index cards. This proves extremely impractical, as they are often mislaid, and he is forced to start again, creating even more work than necessary. Clients Background. My client was born on 5th May 1985 in Chelsea. He went to Dun Raven in Streatham; he was bullied at school, until in year 10 he moved to St William Perkins all boys’ school. Where he excelled in, Music and, Performing arts. He later took a level performing arts, music, ICT, and Textiles. He went on to university, but was expelled after three months. He was interested in dj-ing since a young age, and went on to do it in his spare time, and then constantly after being expelled from university. He then helped out at local venues, at low key parties and occasions. He then went on to take an apprenticeship, and started charging for his services. He then bought his own flat in Woking, with a small studio, where he could focus constantly on his DJ-ing. He has been employed by various clubs such as â€Å"wicked†, â€Å"Lyyne† â€Å"Chameleon† and most recently â€Å"Avenue Q†. His intentions are to raise enough money to be able to go back to university. Identifying the user My client will be the main user of the system, but I will occasionally use the system to check for updates and any possible faults. Statement of the problem My client currently organizes his music collection manually, using index cards and other pieces of paper. This is organised by Artist name. But this proves inadequate and time consuming, as he often loses his lists, resulting in him having to write it all out again. Using valuable time, that could be spent doing something more constructive. Manual solution considered My client could keep his current method of index cards, (organised via artist name) which can prove sometimes useful, as technology can sometimes crash, or have faults. On the other hand index cards can be often lost, resulting the time consuming task of re-writing them all out. Another manual solution would be to use folders to organise his collection, (organised either by artist name, or song name) this is more effective than index cards as they are large, and easier to keep track of. But, could result in a large amount of space being taken up, as the folder collection, would have to be extremely large. Two alternative software solutions considered Mr Cheezeburger could use itunes to organize his music collection, as it is user friendly and very easy to use. Contrariwise to be able to use itunes QuickTime and safari must be downloaded using up more memory, causing the system to be slower, also, an itunes library cannot be transferred to multiple computers in a short space of time. MS Excel could also be used, as it is easy to use, and the cells can be filtered and things can be located quickly and easily. On the other hand it is easy to make errors, and they effect the system long term. Proposed solution justified I have chosen to use MS access because it is easy to use, and it is simple to find things using queries and searches.
