Proposed Revisions to Aeronautical Design Standard-33E (ADS-33E-PRF) Toward ADS-33F-PRF
Abstract
The United States Armys rotorcraft handling qualities performance specification is Aeronautical Design Standard33 (ADS-33).Since ADS-33E-PRF was published in March 2000, many flight tests and research efforts in the United States and abroad haveprovided valuable lessons and data to support potential updates. This report describes proposed changes to ADS-33E-PRF toward anew ADS-33F-PRF. A proposed draft ADS-33F-PRF is included in the report Appendix. The changes encompass major newadditions/updates and a significant number of minor changes. The major additions/updates, described in some detail herein, include:new yaw-axis bandwidth the attitude quickness boundaries; new side-stick inceptor characteristics; new disturbance rejection criteria;new external slung load criteria; and a new slung load MTE. All of the proposed additions and updates, including a significantnumber of minor changes, are described in the Changes from Previous Issues section in the draft ADS-33F-PRF.The existing criteria in ADS-33 are based on current vehicles within the DoD fleet. The FVL family will cover a range of vehiclesizes and speeds not seen before. Continued Army-Navy-NASA S and T research in rotorcraft flight control and handling qualities andgovernment-industry collaboration will be needed to produce the follow-on version of ADS-33 applicable to the FLV family ofvehicles.
