Characteristic of gas jet type IDELCHIK.
| Attribute | Type | Default | Unit | Description |
|---|---|---|---|---|
| ID | Int | Numerical identifier | ||
| NAME | Name | Alphanumerical identifier[1] | ||
| EFAC | Real | 1.0 | Jet efficiency factor[2] | |
| EFAC_FUNC | Ref | Ref to FUNCTION.CONTROL_SIGNAL | FUNCTION.XY. Jet efficiency function – jet efficiency factor [-] vs. relative time [s][3] | ||
| Notes: 1. The total length of a full path of a NAME attribute (including ID and NAME and strings generated by madymo) may not exceed 256 characters. 2. Range: (0, 2]. 3. If specified, the total jet efficiency factor is calculated as the product of EFAC and EFAC_FUNC: efac = EFAC * EFAC_FUNC(t-ttrigger). If not specified the function is taken as 1: efac = EFAC. Note that the value of efac should be in the interval [0, 2] and that the relative time is specified w.r.t. inflator trigger time. | ||||
