Available in PDF, EPUB and Kindle. Book excerpt: An Airworthiness and Flight Characteristics Test of the Boeing Vertol CH-47D helicopter (USA S/N 81-23383) was conducted by the U.S. Army Aviation Engineering Flight Activity. The test was conducted at St. Paul, Minnesota (elevation 704 feet). Edwards Air Force Base (elevation 2302 feet), Bishop (elevation 4120 feet), and Coyote Flats (elevation 9980 feet), California. A total of 148.8 hours (105.4 productive hours) were flown between 25 January and 13 December 1983. Hover, level flight, and autorotational descent performance tests were conducted. Handling qualities tests included static and dynamic stability, maneuvering stability, takeoff and landing characteristics, power management, simulated systems failures, simulated Instrument Meteorological Conditions flight evaluation, and vibration evaluation. Cockpit and subsystem evaluations were also made. The CH-47D exceeded those performance requirements of the Prime Item Development Specification which were evaluated during this test. The Advanced Flight Control System heading select capability and the pressure refueling capability were found to be enhancing characteristics of the aircraft. Three significant shortcomings were found: the poor engine governing system which allows large rotor speed excursions with changes in power setting or airspeed, the high level of cockpit vibrations at and above cruise airspeeds, and an easily excited three-axis airframe oscillation during high power conditions at light gross weight.

This book was released on 1972 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: The second phase of the CH-47C airworthiness and flight characteristics (A and FC) test program consisted of the stability and control test of the production helicopter. The CH-47C was evaluated to determine compliance with the military specification, MIL-H-8501A, with deviations as defined in the detail specification. The helicopter was also evaluated with respect to its mission as a transport helicopter. The CH-47C stability and control characteristics are acceptable for the transport helicopter mission.

This book was released on 1971 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: The CH-47C was flight tested to obtain detailed performance data and to verify compliance of the aircraft with the manufacturer's detail specification and applicable military specifications. The test results show that the helicopter exceeded all performance guarantees and complied with almost all specifications against which it was tested. The performance characteristics of the helicopter are satisfactory for operational use.

Download or read book Airworthiness and Flight Characteristics A FC Test of YAH 64 Advanced Attack Helicopter Prototype Qualification Test Government PQT G 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 1984 with total page 67 pages. Available in PDF, EPUB and Kindle. Book excerpt: The US Army Aviation Engineering Flight Activity conducted an evaluation to determine the increase in power required and the change in handling qualities due to the installation of the AN/ALQ-151(V)2 countermeasures system and associated mission equipment on the UH-60A helicopter. Testing conducted between 23 May 27 June 1984 totaled 12.4 hours. The addition of the Quick Fix System and associated mission equipment created an increase in equivalent flat plate area (F sub e) of 17 sq ft (ft2) for advance ratios (mu) of o.26 and greater. For mu's less than 0.26, the change in F sub e increased above 17 sq ft as a function of thrust coefficient. Handling qualities of the Quick Fix configured YEH-60A were unchanged from a normal utility configured UH-60A and were determined satisfactory. One deficiency, interference between the main rotor blades and the upper elements of the (no. 3 and no. 4) direction finding dipole antennas during ground taxi and four shortcomings were associated with the Quick Fix configuration. Keywords: Equivalent flat plate area; Handling qualities; Level flight performance; Quick Fix Configuration; YEH-60A helicopter.

This book was released on 1984 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: Level flight performance tests were conducted on five EH-1X/EH-1H helicopter configurations to determine the change in drag characteristics with the addition of external mission equipment to the standard UH-1H helicopter configuration. Comparison of data from a baseline test configuration with previously published UH-1H and YUH-1H data indicated approximately 8.0 increase in equivalent flat plate area which was attributed to the external mission antennas, low reflective infrared/optical paint, and heat suppression kit with vertical exhaust ejector. Installation of the M-130 chaff/flare dispensers resulted in a further increase in equivalent flat plate area of 5.0 sq ft. Replacing the vertical exhaust ejector with the hot metal plus plume infrared suppressor, including the ALQ-144 countermeasures jammer resulted in a reduction in equivalent flat plate area of 1.5 sq ft. Installation of the direction finding antennas resulted in no measurable increase in drag. Addition of all external mission equipment and the hot metal plus plume exhaust resulted in a total increased equivalent flat plate area of approximately 11.5 sq ft. from the standard UH-1H helicopter.

This book was released on 1982 with total page 53 pages. Available in PDF, EPUB and Kindle. Book excerpt: The United States Army Aviation Engineering Flight Activity conducted an Airworthiness and Flight Characteristics Tests (A & FC) of a production AH-1S equipped with an M130 Aircraft General Purpose Dispenser System (AGPDS). The A & FC consisted of limited performance and handling qualities tests and was conducted from 12 May through 16 June 1982 at Edwards AFB, California. The tests were conducted to obtain performance and handling qualities data for inclusion in the operator's manual. Installation of the M130 AGPDS on the AH-1S caused negligible effect on power required for level flight. No significant changes in handling qualities were found as a result of the M130 AGPDS.
