查询词典 autorotation

TILT ROTORCRAFT : An aerodyne which derives the whole or a substantial part of its lift for vertical or hovering flight by tilting rotor upward to a position substantially vertical, and in forward flight derives its lift from rotors and/or wings, and is capable of autorotation in the event of power failure.

倾斜旋翼飞机：一种旋翼机，垂直或悬浮飞行时，整个或其中相当一部分之爬升力源自倾斜旋转翼使上升到一个极度垂直的位置，而在向前飞行时，爬升力源自旋转翼和/或机翼，并有能力在发生动力供应中断时自动旋转。

In order to deduce the engine control law during the helicopter autorotation, simulation was made to demonstrate the transient process of the engine when entering the helicopter autorotation condition using normal control law. Based on the existing control law, an improved law was brought forward by magnifying the differential gain of collective pitch "anticipator" and broadening the deceleration limitation.

为确定直升机自转下滑训练过程发动机的控制规律，分析了采用正常控制规律进入自转状态时涡轴发动机的变化过程，提出了在现有控制规律基础上增强动力涡轮转速控制模块中总矩"提前器"作用和适当放宽速率限制值的控制对策。

直升机自转特性的好坏，直接关系到该型机安全性和可靠性。

The landing of a helicopter in autorotation is formulated as a nonlinear optimal control problem.

本文将直升机的自转着陆过程定义为一个非线性的最优控制问题。

The helicopter does not have to be pirouetting when the Autorotation starts.

在执行熄火降落的动作之前，机体不须保持自旋。

Arguably the world's first successful helicopter, this historic machine was badly damaged in June 1939 during autorotation tests.

The height where an impact is not survivable but below which other procedures like "autorotation" are not possible.

高度在不影响生存，但低于其他程序，如" autorotation "是不可能的。

Objective The purpose of this study was to analyse the vestibular autorotation test results in patients with vertigo and disequilibrium and to evaluate rationality of VAT in clinical practice.

The height where an impact is not survivable but below which other procedures like "autorotation" are not possible.

高度在不影响生存，但低于其他程序，如& autorotation &是不可能的。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
