Part 3 and Production Validation Test-Government (PVT-G) for Handbook Verification written by Bartholomew D Picasso (III.) and published by . This book was released on 1982 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Airworthiness and Flight Characteristics Test of the YAH-64 helicopter was conducted. Seventy flights and 70.4 productive hours were flown. Performance testing assessed the probability of meeting the production contract requirements and consisted of an evaluation of hover, takeoff, level flight, forward flight climb and autorotational descent performance. Handling qualities testing determined compliance with selected research and development contract requirements and included standard stability and control tests, an evaluation of slope landing characteristics and instrument flight capability. Additional tests included evaluation of an uprated engine and an external noise survey. The YAH- 64 now meets the performance requirements of the system specification for the production program; the vertical climb and maximum level flight cruise speeds. Slope landing characteristics were satisfactory up to 9 degree lateral slopes and 10 degree longitudinal slopes.

This book was released on 1981 with total page 181 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Airworthiness and Flight Characteristics Test Part 1 of the prototype YAH-64 helicopter (S/N 77-23258) was conducted at three test sites; Palomar Airport, Carlsbad, California (elevation 328 ft). Bishop Airport, Bishop, California (elevation 4120 ft), and Coyote Flats, California (elevation 9980 ft). Approximately 32 productive hours were flown during 45 flights between 30 May and 17 July 1981. Several design changes affecting performance and handling qualities were made to the YAH-64 since the last evaluation (EDT 4) the most significant of which were the changes in tail rotor rigging, the addition of a third DC electrical bus and the incorporation of a Nap-of-the-Earth/Approach mode of operation for the horizontal stabilator. Level flight performances and vibration levels have been slightly degraded since EDT 4, while handling qualities and out-of-ground-effect hover performance remain essentially the same. Numerous anomalies in the operation of the Digital Automatic Stabilization Equipment (DASE) were experienced which may render some of the handling qualities test results suspect. Two deficiencies (both DASE related) were found during this evaluation. Yaw SAS hardovers, and disengagement of the DASE with failure of the No. 2 generator. Nine previously unreported shortcomings (4 DASE related) were found. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: A Handling Qualities Evaluation, Engineer Design Test 1, was conducted of the Hughes Helicopter Company YAH-64 advanced attack helicopter from 22 April 1978 through 1 May 1978 at Palomar Airport, Carlsbad, CA (elevation 320 feet). A total of 15 flights were conducted during 21.8 hours (17.4 hours productive). The objectives of the test were to reevaluate certain flight characteristics which were undesirable during Phase 1 testing, and to assess the effect of design changes on aircraft handling qualities. This phase of the aircraft development was not intended to address all of the undesirable flight characteristics uncovered during the Phase 1 testing. Many enhancing characteristics, deficiencies, and shortcomings, reported during the government competitive test (GCT) remain valid. The YAH-64 continues to have the potential to be developed into an excellent attack helicopter.

Available in PDF, EPUB and Kindle. Book excerpt: First article preproduction flight testing was conducted in Mesa, Arizona (elevation 1387 feet) between 6 August and 29 August 1984. Twenty test flights were conducted for a total of 32.2 hours (22.1 hours productive). Level flight performance and handling qualities tests were conducted to verify that the production aircraft characteristics are the same as those of prototype YAH-64 as tested in Airworthiness and Flight Characteristics (Part 3) tests. The level flight performance and handling qualities of the production aircraft were not significantly different from those of the prototype. Additionally, the performance data presented in the operator's manual is a good representation of the production aircraft performance. One enhancing characteristic was found (the automatic contingency power feature of the T700-GE-701 engine). Two deficiencies were identified (the false indication of engine failures which was previously reported and the poor engine/airframe response characteristics which was previously reported as a shortcoming). Four shortcomings of the prototype aircraft have been corrected in the production aircraft while 13 remain. Additionally, 13 new shortcomings were found. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Engineer Design Test 4 (EDT-4) was conducted using a prototype YAH-64 aircraft. This test was conducted at Palomar Airport, Carlsbad, California, (elevation 328 feet) between 10 and 29 November 1980. Approximately 33 hours were flown during 27 flights. Major changes affecting performance and handling qualities were made to the YAH-64 since the last evaluation (EDT-2). These included a new, digital stability augmentation system, and a redesigned empennage featuring an automatically programmed stabilator and an increased diameter tail rotor. In previous evaluations the flight envelope and scope of test were limited by structural loads and continuous monitoring of those loads was required for all flights. During this test, the flight envelope was much larger and no structural limits were encountered. Hover and level flight performance of the aircraft have been improved since EDT-2. Handling qualities have been greatly improved. The most significant areas of handling qualities improvements were in low-speed flight characteristics, including directional control margins, short-period dynamic stability characteristics (particularly in high speed flight), and in aircraft pitch attitude during approaches and IRP climbs. Three deficiencies were found during this evaluation. The disengagement of the HARS, DASE, and automatic operation of the stabilator, and erroneous activation of the engine out/low rotor speed audio warning tone with failure of the No. 1 generator random failure of the master caution light to illuminate with the illumination of some caution on warning panel segment lights; and the restricted pilot's field of view caused by canopy frame structure during NOE and contour flight.
