Introduction

+his short -anual is not intended to give an overvie of the a&&lied si-ulation -ethods and

their theor. +his docu-ent is rather -eant as a ,rief guide to ena,le the users to or9 ith

the ne version of 'lade and give a short overvie of the overall functionalit and the ne

features of v.08. A -ore detailed docu-ent: an u&date to the 'lade Guidelines v.06 ;1< ill

,e -ade availa,le later this ear.

ith the ne version 'lade has ,een full integrated the aeroelastic si-ulator AS+ ;2M Simulation module

+he )otor * +ur,ine Si-ulation -odules &erfor- a 'lade $le-ent o-entu- ethod

si-ulation of a rotor or a tur,ine. A rotor si-ulation onl contains di-ensionless varia,les

such as ti& s&eed ratio or &oer coefficient. After a tur,ine o,Bect is defined fro- a rotor

ithin the tur,ine si-ulation -odule a nondi-ensionless si-ulation can ,e &erfor-ed

/&oer: inds&eed: etc. A si-ulation is defined fro- the Define Simulation,utton in the

doc9 indo. A range of ti& s&eed ratios or inds&eeds has to ,e defined ,efore the

si-ulation is started ith Start Simulation. Si-ulation results can ,e e%&orted , right

clic9ing on a gra&h and selecting> current rah - e6ort rah: hich e%&orts all curves

that are &lotted inside the gra&h as a .t%t or .csv file.

In the structural ,lade design -odule ;6< a si-&le structural -odel for the ,lade can ,e
