Book excerpt: A Preliminary Airworthiness Evaluation was conducted for the AH-64A equipped with the Air-to-Air Stinger (ATAS) missile system. The first phase was an evaluation of the effects of the ATAS installation on the handling qualities on the AH-64A. The second phase was a human factors evaluation of the installation of a fully operational preproduction ATAS system using captive flight training Stinger missiles, Tests were flown in the eight Hellfire missile configuration. Two Stinger missiles with launcher and mounting hardware were mounted at each wing tip. Test results were compared with data obtained during previous testing and evaluated against the AH-64 System Specification. Handling qualities of the AH-64A with the ATAS system installed were quantitatively and qualitatively evaluated and found to be essentially the same as the basic AH- 64A. Specific shortcomings associated with the ATAS system were: poor integration of the Air-to-Air Stinger missile system, which is not directly compatible with the MIL STD 1553 data bus of the AH-64; insufficient ATAS sighting symbology, which does not provide the copilot/gunner with accurate missile seeker line of sight relative to the selected sight line of sight except in FLIR wide field of view; reduction in storage space imposed by the ATAS installation in the aft storage bay; location of the repositioned chaff fire switch on the cyclic hand grip; and the manual reset feature of the ATAS missile sequencing logic. The absence of an altitude encoding feature in the installation of the AN/APX-100(V) transponder was a shortcoming not associated with the ATAS modification. Seven recommendations specific to the ATAS installation are made.

This book was released on 1984 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aircraft was operated at gross weights up to 10,400 lb, up to 11, 340 feet density altitude and at a lateral center of gravity (cg) range from one inch right to approximately three inches left. The asymmetric loadings were caused by the various combinations of armament configurations. The change in equivalent flat plate area compared to the clean aircraft for each configuration varied as a function of airspeed. At 130 knots true airspeed (KTAS), the increased flat plate area was 4.2 square feet for the Launcher configuration, 4. 8 square feet for the TOW configuration, 6.6 square feet for the Hellfire and Hellfire/TOW configurations, and 7.8 square feet for the Stinger/Hellfire/TOW configuration. The increase in flat plate area for the Stinger/Hellfire/TOW configuration reduced maximum level flight speed for normal rated power by approximatley 8 KTAS. With the exception of the two armament related shortcomings listed below, the handling qualities and the reactions to system failures of the AH-1S (MC) were not significantly changed by the asymmetric loading of the various armament configurations. Four shortcomings were noted and follow in decreasing order of importance: (1) the high left rolling response to a sudden engine failure at power settings above 75% torque; (2) the undesirable maneuvering stability characteristics above 1.4 g's; (3) insufficient left pedal margin available in right sideward flight above 10 knots in the Hellfire and Hellfire/TOW configurations; and (4) insufficient left pedal margin available for ball-centered forward flight below 30 KCAS in the armament configurations with left lateral cf offset. A CAUTION is recommended for inclusion in the operator's manual dealing with.

Moe and published by . This book was released on 1979 with total page 43 pages. Available in PDF, EPUB and Kindle. Book excerpt: The AH-1G helicopter with the HELLFIRE modular Missile System (HMMS) and the Airborne Target Acquisition Fire Control System (ATAFCS) is being used as a surrogate trainer for the YAH-64 helicopter. The United States Army Aviation Engineering Flight Activity was tasked to provide quantitative and qualitative data on the handling qualities of the helicopter, obtain limited level flight performance data, and obtain limited handling qualities of the helicopter with only the ATAFCS installed. The test helicopter was a production AH-1G helicopter (212 tail rotor) modified with an ATAFCS mockup and carrying eight HELLFIRE missiles. Six productive flight test hours were flown in six flights. No shortcomings or deficiencies attributable to HMMS and ATAFCS installation were found. The AH-1G helicopter, with HMMS and ATAFCS installed, exhibits an additional equivalent flat plate area of 4.0 ft2 compared to the standard AH-1Q helicopter. The handling qualities of the helicopter with only the ATAFCS installed are essentially the same as the production AH-1G helicopter. (Author).

Book Synopsis Preliminary Airworthiness Evaluation AH-1S Helicopter Equipped with a Garrett Infrared Radiation Suppressor and an AN/ALQ-144 Jammer by : Gary L. Bender
Download or read book Preliminary Airworthiness Evaluation AH-1S Helicopter Equipped with a Garrett Infrared Radiation Suppressor and an AN/ALQ-144 Jammer written by Gary L. Bender and published by . This book was released on 1978 with total page 79 pages. Available in PDF, EPUB and Kindle. Book excerpt: The tests were conducted to determine the effects of installation of the IRS and the AN/ALQ-144 infrared jammer. There was no apparent effect on power required to hover and only a small increase in power required to maintain level flight. Because of a power-available degradation, however, there was a loss of 220 pounds payload in an out-of-ground-effect hover at 4000 feet, 35 C. Additionally, at 2000 feet, 25 c, and 9300 pounds gross weight, there was a reduction in maximum level flight airspeed of 3.5 knots true airspeed in the clean wing configuration. No degradation in handling qualities was caused by IRS or infrared jammer installation. However, one deficiency and six shortcomings inherent in the basic AH-1S were noted. The nonadjustable ventilation system is a deficiency because it blows dirt and dust into the pilot's eyes during operations from unprepared surfaces.

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 1987 with total page 118 pages. Available in PDF, EPUB and Kindle. Book excerpt: The airworthiness evaluation of the UH-60A helicopter configured with the External Stores Support System (ESSS) and 16 HELLFIRE (4 HMMS) missiles installed was conducted at the Sikorsky flight test facility at West Palm Beach, Fl (elevation 28 feet). A total of 16.2 productive hours during 18 flights were flown between 21 May and 3 June 1987. Tests were conducted to determine handling qualities and performance of the UH-60A in the 16 HELLFIRE (4 HMMS) missile system configuration at an average mission gross weight of 17,000 pounds. The handling qualities of the UH-60A with the 16 HELLFIRE (4 HMMS) missile system installed were essentially unchanged from those previously reported for the UH- 60A in the normal utility configuration. The equivalent flat plate area of the 16 HELLFIRE (4 HMMS) missile system was determined to be 11 square feet over that of the UH-60A in the ESSS only configuration. One miscellaneous observation was made regarding the initial installation and fit of the production ESSS fairings. Keywords: Helicopters; Air to surface missiles; Guided missile launchers; Handling qualities/ HELLFIRE modular missile system; Performance decrement.
