Quick start basics - Performance Deck Generation

 

Create a case (accept configuration changes) and name it "Performance Deck' and set the run case type to St. St. Series.

 

Drag a flight envelope scheduler component from the case component library to the newly created case Performance_Deck. The model window pane should resemble something like the figure beneath.

 

TS_BIGFAN_FlEnvSchedCase

 

Open the data entry window of the flight envelope scheduler to configure the flight envelope. On opening the following window is presented:

 

TS_BIGFAN_FlEnvSchedWindow1

 

Basically three control parameters are available for creating the basic flight envelope. Note that the dTs parameter is disabled, but can be enabled by setting the Ambient/Flight conditions model type to ISA+.

 

Setting a Start, End and Incr value for each of the flight envelope parameters will automatically create an incremented list from start to end. Pressing the insert key for a selected row in a list will insert a new row. Setting the limits will result in limiting output to area's the airplane is not capable of, or limited to fly. Change the input to the input listed in the figure below:

 

TS_BIGFAN_FlEnvSchedWindow2

 

And the power control setting accordingly to the picture below:

 

TS_BIGFAN_FlEnvSchedWindow3

 

Press Graph to generate the input data (accept Apply Envelope) which will open a graphical representation of the flight envelope. By generating the flight envelope, the appropriate input data will be generated in the St.St. OD Series input grid of the Ambient/Flight Conditions and in the St.St. OD Series input grid of the rotor speed controller.

Close the flight envelope graph and close the flight envelope scheduler. Since the simulation contains many points, the calculation time is considerable, and user interaction when errors occur is not preferred. By setting the Options -> Transient/Series... -> then by checking the Batch Mode option user interaction is not required.

 

Run the simulation to create the performance deck data.
