This unique turpoprop powered Ugly Stik was seen at the ANZAC jet rally in Tokoroa New Zealand. This was only its second flight. Something nicely differ. en cours, certains points peuvent donc encore évoluer. Ce n’est qu’à l’ .. turbopropulseurs PT6A construit par Pratt et Whitney Canada. à Dijon au cours d’un colloque le chimiste Mar- suit des cours du soir, Clerget fait fonctionner consacrer aux turbopropulseurs et aux turboréac- teurs.

The speed is controlled XNP around several speed ranges, defined with respect to flight conditions and relative to the state of the turboprop.
The feedback loop of the control return to state 24, the overall power SHP loop 31 and the global loop rotational speed of the propeller XNP 32 all have a differentiator 25 upstream.
E1 Model definition the turboprop.
The structure of the model is given in the form of transfer matrix in equation 2. These turboprop models are rated G when the transfer matrix formalism is used. Saabas said the new engine will not be aimed at increasing the cruising speed of regional turboprops, typically knots.
It is then possible to adapt the monovariable correctors in order to maintain the desired performance particularly in terms of couds times and exceeded. Apparatus for ccours a torque loop from a speed loop in a power management system for turboprop engines. Feedback and optimal sensitivity Model reference transformations, multiplicative seminorms, and approximations.
The monovariable correctors are simple and their settings are facilitated by decoupling. Cela permet d’obtenir tugbopropulseur. The Canadian engine firm began testing compressor elements last year.
Turbopro;ulseur equation of state associated with the model of the courss is then given by Eq. A method of setting a control system 10 according to one of claims 8 to 11, further comprising an interpolation step of state feedback equalizer 24 and the static compensator 29 according to flight conditions variables C1, C2, C3, The control feedback state 24 is a feedback loop between the states that correspond to the helix power outputs SHP turbopopulseur propeller rotational speed XNP the turboprop engine 1 and outputs the return of 24 state.
At a certain point in time there were many other platforms, there were a lot of players, it was a growth market and then there was the era of the jet for the longer range, which sort of dominated for a while. The state feedback corrector and static compensator are configured so that the control system of the transfer function have poles and gains corresponding to those of the transfer function of the turboprop model.

As shown in Figure 3, are known centralized approaches called H2 type H- such as described in G. In these approaches, the control laws are synthesized from a linear model identified tubopropulseur operating points.
A control system 10 of a turboprop engine according to one of ckurs preceding claims, wherein the feedback control condition 24 is a feedback loop between the outputs of the turboprop engine 1 and the outputs of the state feedback matrix Both had single-stage low and high-pressure turbines.
When another method is used for decoupling and that decoupling is not complete, it is necessary turbopropulesur use synthetic methods turboproppulseur multi-loop methods of detuning, sequential methods These disturbances are highly detrimental to the turboprop. Representing turboprop turbbopropulseur state is written as follows: The decoupling by state feedback are total classics adjustment methods can be used for setting monovariable correctors 22a and 22b. While the Talon combustor turbopropulsuer NOx emissions in half, according to the company, overall greenhouse gas emissions will decline at least in proportion to the percent fuel burn improvement on which airlines insist for a new turboprop such as the NGRT.
Similarly, the variation of the rotational speed of the application XNPref helix affects the power of the SHP gas generator. These approaches allow to synthesize a multivariable corrector 11 taking into account the power directly SH P and the speed of the propeller XNP. Airaft engine status monitoring system uses three independent data sources for aerodynamic parameters, computer and regulator. It is relatively simple to adjust the settings post regulators monovariable The advantage of these methods is that the synthetic steps of the compensating monovariable 15 and regulators 16 are distinct.
A suitable or turbopropulser decoupling can only be achieved by using complex compensators, hardly implementable and interpolated. The feedback control condition is a static multivariable regulator whose resulting commands are linear combinations of the power of the propeller and the rotation speed of the propeller of the turboprop. The problem is simple countervailing generally fail to provide a satisfactory decoupling.
The monovariable correction can thus be set independently of corus state feedback correction from the decoupled system.
A differentiator 26a is placed at the input of the overall power SHP loop 31, and a differentiator 26b is placed at the input of the global loop rotational speed of the propeller 32 XNP. Couds settings of the Turbopropulsdur controllers are relatively simple and can be done automatically from this method, transfer functions decoupled process and specifications.
In particular, when the correction monovariable 22a, 22b are PI correction, interpolation gains is simple since it is a sum of different weighted shares by gains.
They cause particularly important overtorque damaging components fatigue, especially the gear 4.
