연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

A system and method for conducting one engine inoperative (OEI) flight procedures training in a dual-engine helicopter includes a multi-function OEI training switch that is operative to initiate OEI flight procedures training by selecting one of said engines as the single operative engine for OEI flight procedures training, and a training function module that is: (1) operative to establish suppressed 30-second, 2-minute, and maximum continuous OEI operating limits for selected engine operating parameters to limit the actual power provided by said powerplant system during OEI flight procedures training; and (2) operative to generate biasing factors to control the operation of the parametric indicators for the selected engine operating parameters during OEI flight procedures training. During OEI flight procedures training, the training function module limits the actual power output of the helicopter powerplant system to the suppressed 30-second, 2-minute, or maximum continuous OEI operating limits, as selected by the pilot, while simultaneously utilizing the biasing factors to cause the parametric indicators of the selected operative engine to provide display indications to the pilot that the selected operative engine is operating at the actual 30-second, 2-minute, or maximum continuous OEI operating limits, as applicable.

[ What is claimed is:] [1.] A system for conducting one engine inoperative flight procedures training in a dual-engine helicopter, comprising:a powerplant system for generating the power required for normal dual-engine and OEI flight operations of the dual-engine helicopter;a collective control system operative to provide control inputs to said powerplant system to control the normal dual-engine and OEI flight operations of the dual-engine helicopter;said powerplant system includingleft and right engines, each of said engines having design power ratings established therefore to limit the power output of said powerplant system during normal dual-engine flight operations and having 30-second, two-minute, and maximum continuous OEI power ratings established therefore to limit the power output of the single operative engine during OEI flight operations,a plurality of sensors associated with each of said engines for monitoring operating parameters thereof and generating sensor signals representative of said operating parameters of each of said engines,a cockpit instrument display system that includes parametric indicators for said operating parameters of each of said engines that are operative in response to said sensor signals to display indications representative of said operating parameters,a fuel subsystem fluidically interconnected to each of said engines and operative to provide fuel thereto,a DECU electrically interconnected to each said fuel subsystem and operative to regulate fuel flow therefrom to said powerplant system for regulating the power output of said powerplant system to control dual-engine and OEI flight operations of the dual-engine helicopter, said DECU being operative to automatically set said 30-second OEI power rating in response to an OEI condition to limit the power output of the single operative engine of said powerplant system during OEI flight operations, and being further operative in response to first and second activation signals to set said 2-minute and maximum continuous OEI power ratings as applicable to control the OEI flight operations of the dual-engine helicopter by limiting the power output of the single operative engine of said powerplant system to said 2-minute and maximum continuous OEI power ratings as applicable during the OEI flight operations, andsaid collective control system having integrated in combination therewith an OEI select switch that is operative to select said 2-minute and maximum continuous OEI power ratings as appropriate during OEI flight operations and that is operative, in response to selection of said 2-minute OEI power rating or said maximum continuous OEI power rating to generate said first and second activation signals to cause operation of said DECUs;a multi-function OEI training switch that is operative to initiate OEI flight procedures training by selecting one of said engines as the single operative engine for OEI flight procedures training and generating a control signal corresponding thereto; anda training function module that isoperative to establish suppressed 30-second, 2-minute, and maximum continuous OEI operating ratings for selected engine operating parameters to limit the actual power provided by said powerplant system during OEI flight procedures training,operative to generate biasing factors to control the operation of said parametric indicators for the selected engine operating parameters during OEI flight procedures training,automatically operative in response to said control signal from said multi-function OEI training switch to set said suppressed 30-second OEI operating limits wherein the power output of the single operative engine is limited to said suppressed 30-second OEI operating limits during OEI flight procedures training,automatically operative in response to said control signal from said multi-function OEI training switch to set said biasing factors associated with said suppressed 30-second OEI operating limits wherein said parametric indicators for said selected engine operating parameters provide display indications indicative of said 30-second OEI power ratings,operative in response to said first activation signal generated by said OEI select switch to set said suppressed 2-minute OEI operating limits wherein the power output of the single operative engine is limited to said suppressed 2-minute OEI operating limits during OEI flight procedures training,operative in response to said first activation signal generated by said OEI select switch to set said biasing factors associated with said suppressed 2-minute OEI operating limits wherein said parametric indicators for said selected engine operating parameters provide display indications indicative of said 2-minute OEI power ratings,operative in response to said second activation signal generated by said OEI select switch to set said suppressed maximum continous OEI operating limits wherein the power output of the single operative engine is limited to said suppressed maximum continuous OEI operating limits during OEI flight procedures training, andoperative in response to said second activation signal generated by said OEI select switch to set said biasing factors associated with said suppressed maximum continuous OEI operating limits wherein said parametric indicators for said selected engine operating parameters provide display indications indicative of said maximum continuous OEI power ratings.
