Available in PDF, EPUB and Kindle. Book excerpt: An evaluation of the anti-icing and de-icing systems was conducted on a leased airplane. The anti-icing system was found satisfactory. It was recommended that the L-23F Airplane be retrofitted with a self-contained pressure system and de-icing boots that would equal or surpass the operational suitability of the de-icing system used on the L-23D. The anti-icing systems and the de-icing systems tested were lightweight pneumatic boot de-icing system and an electrothermal anti-icing system for the wings, empennage, propellers, and windshield.

Available in PDF, EPUB and Kindle. Book excerpt: The army originally procured three model L-23F Airplanes which represented a manufacturer's sponsored product improvement of the Army's 'off-the-shelf' L-23D. One of the original three models was service tested by the Aviation Board; some shortcomings, but no discrepancies, were observed. Subsequently, the Army procured additional L-23's. Meanwhile, in addition to correcting some of the shortcomings reported as a result of service test, sufficient product-improvement items were incorporated to warrant a confirmatory test of the current production configuration. Because of the short time allotted for confirmatory tests, evaluation of the anti-icing and de-icing equipment could not be accomplished. Therefore, CG, USCONARC, has directed that a separate evaluation of the anti-icing and de-icing systems be conducted in conjunction with the AO-1 icing-spray tests at Wright-Patterson AFB. (Author).

This book was released on 1990 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aerodynamic effects of aircraft ground deicing/anti-icing fluids is a topic that has received increasing attention in recent years as the use of these fluids becomes more widespread and sophisticated. An important consideration with respect to the use of these fluids is the effect of residual fluid remaining on the aircraft during the takeoff roll and initial climb. A flight test program to determine these effects on the takeoff and climb performance for two general aviation aircraft was conducted. The flight tests were performed in Topeka, Kansas, and Duluth, Minnesota. Results indicate that the presence of the deicing/anti-icing fluids on the aerodynamic surfaces of the test airplanes can reduce aerodynamic lift and increase liftoff airspeeds. However, the flight test pilots reported no obvious changes in the performances of handling characteristics of the aircraft.

Available in PDF, EPUB and Kindle. Book excerpt: The U.S. Army Aviation Engineering Flight Activity evaluated the improved OV-1D anti-icing system from 28 January to 21 February 1988 at Duluth, Minnesota. Ten flights (6.5 hours cloud immersion) in artificial conditions and four flights (5.8 hours cloud immersion) in natural conditions were conducted. One enhancing characteristics, nine deficiencies, and three shortcomings were identified. The windshield anti-ice system, when working, enhances safe mission accomplishment. The nine deficiencies were: the inability of the pneumatic deicing system to remove wing and empennage leading edge ice accumulations; the excessive number of AC generator drive shaft failures; the ice accretion characteristics of the engine inlet cowl at temperatures colder than -15 degrees C; the ice accretion and shedding characteristics of the propeller spinner afterbody; the numerous dropouts of one or both windshield anti-ice systems and lack of failure warning to the pilot; the numerous dropouts of the AC generators during flight, the increased pilot workload required to reset them and the distraction caused by illumination of the Master Caution light; the numerous converter dropouts during normal operations, the increased pilot workload required to reset them, and the resulting pilot distractions caused by illumination of the Master Caution light; the numerous inverter dropouts and the ensuing delay and actions required to reestablish flight essential and normal inverter loads; the fact that an anti-ice controller may not be functioning properly and still pass its Operational Readiness Test.

Available in PDF, EPUB and Kindle. Book excerpt: ?Pub Inc Airports that operate in cold climates are required by the FAA to de-ice aircraft and runways. The most common method involves the use of glycol-based aircraft de-icing/anti-icing fluids (ADAF). The majority of these fluids contain either propylene or ethylene glycol that act as freezing point depressants, along with additives such as corrosion control inhibitors, surfactants, and wetting agents. Historically, the runoff of spent fluids from aircraft and pavement de-icing/anti-icing operations has been difficult to manage, resulting in significant discharges to surface waters on both a national and global level. Currently, best-practice treatment of airport storm water containing ADAF is geared for glycol-rich wastewaters, with the treatment efficiency being measured by reduction of BOD and nutrient levels in the effluent. The objective of the thesis was to assess whether the traditional parameters (BOD, COD, and pH) most frequently used to monitor the treatment and release of airport stormwater effluent containing de-icing fluids were adequate indicators of the effluent quality. Current literature was used to evaluate the chemistry, environmental fates, persistence in the environment, and toxicity of two classes of compounds, glycols and benzotriazoles. Glycols were shown to be readily degraded in the environment and relatively non-toxic. Benzotriazoles were shown to be resistant to degradation, persistent, and toxic in the environment. The fate of both of these types of compounds was then evaluated in best practice treatment methods for airport stormwater. Glycols were shown to be effectively treated and benzotriazoles were projected to be recalcitrant. The research supports the hypothesis that using BOD, COD, and pH as measures of suitability of return to the environment for treated stormwater containing spent ADAF is inadequate. New additives and more sophisticated ADAFs affect the toxicity of the effluent and require treatment processes that effectively treat all of the constituents of the fluid.
