This book was released on 1977 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: The United States Army Aviation Engineering Flight Activity conducted a Preliminary Airworthiness Evaluation of the EH-1H Helicopter Quick Fix Phase 1A to determine the effects of the installation of the AN/ARQ-33 radio countermeasures system and its associated equipment on aircraft handling qualities. The helicopter was tested from 18 through 23 August 1977 at Naval Air Station, Pensacola, Florida. During the tests, nine flights totaling 8.5 productive flight hours were flown. The handling qualities of the EH-1H helicopter were determined to be satisfactory with the exception of inadequate directional control in right sideward flight. An enhancing characteristic noted was the simultaneous antenna retraction systems. Inadequate directional control at right sideward velocities between 5 and 15 knots true airspeed was a deficiency. Two shortcomings were noted: the susceptibility to damage of the right FM 10-120 homing antenna during preflight/maintenance operations and the susceptibility to damage of the FM 10-242 communications antenna during running takeoff/landing maneuvers.

Book Synopsis Preliminary Airworthiness Evaluation of a UH-1 Equipped with a Terrain Mapping Receiver Antenna by : Frederick W. Stellar
Download or read book Preliminary Airworthiness Evaluation of a UH-1 Equipped with a Terrain Mapping Receiver Antenna written by Frederick W. Stellar and published by . This book was released on 1987 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: The preliminary airworthiness evaluation of the UH-1H helicopter equipped with the receiver antenna of the Terrain Mapping Radar System was conducted in Lakehurst, New Jersey, between 21 November and 8 December 1986. The evaluation required 12 flights for a total of 14.8 hours, or which 12.0 hours were productive. Performance, handling qualities, and structural dynamic response tests were conducted. The modified UH-1H equipped with the receiver antenna demonstrated adequate handling qualities for the terrain mapping mission. However, the proposed mission profile requires extensive operation of the helicopter in an out-of-ground effect (OGE) hover. Although the handling qualities are acceptable, the degraded autorotational characteristics may preclude a safe autorotational landing in the event of a sudden engine failure at an OGE hover below 1000 feet above ground level. The minimum directional control margin and high pilot workload to maintain heading during low speed flight were a shortcoming. Three additional shortcomings were found during the evaluation.

Book Synopsis Combined Preliminary Airworthiness Evaluation and Airworthiness and Flight Characteristics Evaluation of the UH-1H with Preproduction Hub Spring and Composite Main Rotor Blades Installed by : Gary L. Skinner
Download or read book Combined Preliminary Airworthiness Evaluation and Airworthiness and Flight Characteristics Evaluation of the UH-1H with Preproduction Hub Spring and Composite Main Rotor Blades Installed written by Gary L. Skinner and published by . This book was released on 1988 with total page 53 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Army has incorporated a main rotor hub spring on the UH-1H helicopter designed to reduce large main rotor flapping angles which occur during some flight maneuvers. Composite main rotor blades (CMRB), also incorporated, are intended to increase performance and to improve reliability and survivability of the UH-1H. A preliminary airworthiness evaluation was conducted to determine suitability of the combined preproduction CMRB and hub spring configuration for compliance with the CMRB Critical Item Development Specification (CIDS). Due to high vibration characteristics and the occurrence of cyclic control feedback contributing to loss of aircraft control associated with CMRB, additional testing was conducted for comparison with standard metal main rotor blades (STD) and composite main rotor blades constructed with production tooling (PROD CMRB). Flight testing was evaluated under a variety of operating conditions from field elevations of 2302 ft to 9980 ft. Some improvement was noted in out-of-ground effect hover performance with PROD CMRB compared to CMRB, while level flight performance of the CMRB and PROD CMRB was not significantly different. Performance improved for the PROD CMRB compared to STD, but did not meet CIDS requirements. Handling qualities are similar for CMRB and PROD CMRB, and deteriorated when compared to STD with regard to maneuvering characteristics and main rotor speed control during autorotation. (edc).

Download or read book Preliminary Airworthiness Evaluation: UH-1H Helicopter Equipped with Multiple Target Electronic Warfare System (MULTEWS) written by Vernon L. Diekmann and published by . This book was released on 1978 with total page 187 pages. Available in PDF, EPUB and Kindle. Book excerpt: The United States Army Aviation Engineering Flight Activity conducted a Preliminary Airworthiness Evaluation (PAE) of a UH-1H helicopter equipped with a Multiple Target Electronic Warfare System (MULTEWS) from 13 August through 2 December 1977. The evaluation was conducted at Edwards Air Force Base, California, and required 45 flights for a total productive flight time of 41 hours. The test program was terminated when the test aircraft sustained major damage during height-velocity testing. The addition of the MULTEWS equipment to the UH-1H airframe caused significant degradation in performance and handling qualities. Changes in the operator's manual should be made to reflect the changes in performance for MULTEWS configured aircraft. The MULTEWS installation also generally degraded the vibration characteristics of the UH-1H, increased structural loads, increased the maintenance workload, and degraded aircraft crashworthiness. The degradation in performance and handling qualities as well as the excessive vibrations and structural loads in the MULTEWS configured aircraft were attributed to the extremely high drag and turbulent wake of the externally mounted MULTEWS components.

This book was released on 1986 with total page 97 pages. Available in PDF, EPUB and Kindle. Book excerpt: Performance, handling qualities, and overall engine-airframe compatibility were evaluated to substantiate an airworthiness release and appropriate restrictions in the operator's manual. These tests were conducted at Bakersfield, Edwards AFB, Bishop, and Coyote Flats, California. Thirty-four flights were conducted for a total of 26.3 productive flight hours. the performance, handling qualities, and overall engine-airframe compatibility of the aircraft with the T53-L-13B engine are unchanged from those with the T53-L-13B engine when the aircraft is operated within the power-available capability of the -13B. Two shortcomings were identified: (1) poor torque gauge readability, and (2) ignition key location. Engine exhaust impingement on the tail boom produced skin temperatures high enough to cause loss of tail boom structural strength. No engine installation or maintenance problems were encountered during the evaluation.

This book was released on 1980 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: A limited performance and handling qualities evaluation and an engine and transmission cooling survey of an AH-1S (PROD) Helicopter equipped with a substitute straight exhaust pipe was performed at Edwards Air Force Base between 20 and 23 August 1979. A total of 8 hours, 6.3 of which were productive, was required. No significant changes in performance or handling qualities were found as a result of the substitute straight exhaust pipe installation. The engine and transmission cooling characteristics were similar to those of a production AH-1S and were satisfactory. No previously unreported shortcomings or deficiencies were identified. (Author).

Approximately 19 productive hours were flown during 24 flights between 17 March and 27 April 1984. The Kellett ferry tanks increased the equivalent flat plate area by 2.0 sq ft. One deficiency noted during the evaluation was the lack of crashworthiness of the external fuel tanks. Four shortcomings associated with the installation of the external fuel tanks were found.
