Wikipedia. The Allison T4. Allison Model 5. American turboprop engine composed of two Allison T3. Design and developmenteditThe T4. Allison in 1. 94. Apollo 13 Mkv Rapidshare Er. W turboprop engine. Taking advantage of this effort, the US Navy awarded Allison a contract for the design and development of a 4,1. W turboprop engine. The resulting T4. Allison T3. 8 A 1 power sections side by side with a common reduction gearbox powering contra rotating propellers. Similar in layout to the Armstrong Siddeley Double Mamba, the T4. Double Mamba, where each Mamba power section drove either the front or the rear propeller separately. The T3. A 1 power sections each contained 1. A combining reduction gearbox was driven via extension shafts from the power sections. Each transmission shaft incorporated a clutch to allow the power sections to be run independently. T4. 0 engines on the XP5. Y 1 prototype in 1. Accessories included a Master Control Unit, mounted above the compressors, and an air driven starter on the gearbox. The compound reduction gear had an overall reduction ratio of 1. Anti icing for the air intakes was supplied by compressor bleed air. TECHNICAL PAPERS.

The Allison T40, company designation Allison Model 500, was an early American turboprop engine composed of two Allison T38 power sections driving a contrarotating. What You Need to Know About Pressurereducing Valves. In a Hydraulic System, you are most likely aware that the main system pressure is maintained by the system. The contra rotating propeller consisted of two 1. Aeroproducts propellers fitted to concentric shafts. Testing of the XT4. June 1. 94. 8, revealing some major vibration problems from the reduction gearbox due to mis matched noise frequencies caused by poorly designed gear teeth. The de coupling system, designed to disconnect a power section in the event of failure worked successfully. During a run in a test cell one power section developed a major oil leak and an attempt to shut it down failed because the engine carried on running on the leaking oil. After many attempts to shut it down the offending power section could only be shut down by destroying the compressor with buckets of nuts and bolts thrown down the intake, proving the de coupling system. First flight test of the T4. Convair XP5. Y flying boat on 1. April 1. 95. 0 fitted with four T4. A 4 developing 5,2. W. Service use of the T4.

The major problems of the T4. As the individual power plants were clutched into the gearbox, it was intended in most instances that the aircraft could cruise on one half of the engine and only engage the second power section when there was need. In practice the system did not work well. Failure to recognize that one of the T3. Douglas XA2. D 1 and its pilot on 1. December 1. 95. 0. Allison T4. The company proposed the Allison Model 5. T4. 4, with three power sections, but none were built and the project was cancelled. Allison T5. After the initial limited success of the T4. US Navy sponsored development of a new turboprop about 2. T4. 0, but this work was soon overtaken by the Allison T5. Allison 5. 01 D and development was cancelled. Operational historyeditThe first aircraft to fly with the T4. Convair XP5. Y 1 patrol aircraft prototype. As flying boat patrol aircraft became redundant, the US Navy changed the role of the aircraft from Anti Submarine Warfare to Transport. Modifications to the XP5. Y 1 such as provision of air conditioning and pressurisation produced the Convair R3. Y Tradewind, which was to become the only aircraft using the T4. These large four engined flying boats served primarily between NAS Alameda and Hawaii during the mid 1. Martin Mars flying boats. There were numerous problems with the T4. One resulted in near disaster in 1. R3. Y managed to land with a runaway engine, resulting in a collision with a seawall. This event gave the US Navy one more reason to ground the R3. Y, which it did soon after. The only other aircraft to be produced in any quantity to be powered by the T4. Douglas A2. D 1 Skyshark. Of the sixteen examples built, the twelve used for evaluation suffered similar problems to the R3. Y. Propeller control problems and gearbox failures were among the more common problems. The T4. North American A2. J 1 Super Savage but the poor performance of the aircraft and continuing difficulties with the engines forced cancellation in favour of the Douglas A3. D Skywarrior. 1The most notable successes of the T4. Convair XFY 1 Pogo, Lockheed XFV 1 and the Hiller X 1. Fitted with the more powerful 7,1. YT4. 0 A 6 the XFY 1 flew the first full flight from vertical take off to horizontal flight and back to vertical flight for landing, of a fixed wing aircraft, in November 1. Continuing concerns over propellers and the poor payload and performance precluded further development. Some flying was carried out with the Hiller X 1. Limited flying was carried out by the two Republic XF 8. INTERNOISE2014 inter. Melbourne Convention and Exhibition Centre, Melbourne Australia, 1619 November 2014. Table of Contents.
