Next, we need to research our problem to know how to create an effective solution. This is our problem: the fins provided are not up to our standards. Designing a custom fin usually means that you don't think the ones included will work the best. Two example constraints are: being allowed to only use a certain material or needing to maximize certain criteria about our design to have the best solution.Ī problem is a need that requires a solution. Constraints are boundaries within the problem. Along with the problem, we need to identify the constraints. The first part of of the EDP is to find the problem. This can be seen in the following snippet of a log file:ġ0592 TRACE n.s.o.s.BasicEventSimulationEngine - Handling event FlightEventġ0592 DEBUG n.s.o.s.BasicEventSimulationEngine - detected Motor Burnout for motor 1.03 on stage 1: Stageġ0592 TRACE n.s.o.s.BasicEventSimulationEngine - Obtained event from queue: FlightEventġ0592 TRACE n.s.o.s.BasicEventSimulationEngine - Remaining EventQueue =, FlightEvent]]ġ0592 INFO n.s.o.s.BasicEventSimulationEngine - => 1.03115 from Branch: Sustainer - Branching: Stage -ġ0593 TRACE n.s.o.s.The EDP is used to create a solution to a problem. If second stage IGNITION is triggered byĮJECTION_CHARGE it is filtered out, and second stage IGNITION fails to If STAGE_SEPARATION is inserted first, theįilter in BasicEventSimulationEngine.java ignoring events fromĬomponents that are no longer attached to the rocket drops ignoresĮJECTION_CHARGE. When the events STAGE_SEPARATION and EJECTION_CHARGE are both triggered byīURNOUT, both events occur simultaneously and either can be inserted * missed reversing the operands in the calculation of last bit of impulse * Little bit more massaging for clarity (replace avgImpulse with impulse)
Fin shape rocket code#
* Code clarification should make no difference to results Small number and then adding doesn't introduce any instabilities I'mĪdd parentheses to clarify that values are being multiplied by time
Comment said it was for numerical stability multiplying by a Remove test for short time interval before first data point in thrustĬurve. * Fix Average Thrust Calculation (fixes issue openrocket#441) * Fixes repeated bug in Presets/Material Loading - inconsistent test criteria Changed implementation of RadiusMethod.*.getRadius() Previous function did not make sense, where implemented in FinSet.Ģ. renamed getOuterRadius() => getBoundingRadius() * tightened access specifiers in FinSet.java
* cleanup up unused imports in core/test/net/sf/openrocket/rocketcomponent/* * may now create and drag a point in one click. * run configuration and jar paths are now cross-platform * added jar artifact for IDEA Intellij build * added shared build configurations for Intellij at. * Updated dependencies for running from intellij it is now a second, expanded, different colored box. * reworks FreeformFinSet Selected point display. * Adding new points to FreeformFins are now placed at the mouse cursor * separated FinSet Tests into files corresponding to FinSet, TrapezoidalFinSet, and FreeformFinSet * FinPointFigure contents are bottom-aligned, properly sized. if the visible bounds are larger than the requested scale bounds, then the figure is expanded to match. * AbstractScaleFigure now stores (& requires!) the visible bounds when setting zoom/scale. * May now delete points again, in the FreeformFinSetConfig window * renamed FinSet#fins => FinSet#finCount to make it's meaning more explicit * Moved fins from core-body to booster-body (they are now doubly-instanced) adjusted tests to accept this. * Fixes the way BarrowmanCalculator handles instancing, particularly for ComponentAssemblies * BarrowmanCalculator no longer multiplies instanced leaf nodes. added unittests for fin count loading/saving/creation * Fins default to instance count / fin count = 1 * Clicking in fin-point figure now calculates closest segment correctly * implemented FinPoint SelectedIndex Indicators * Addes back in ConfigDialog outside spacing. * clicking away from points now longer causes an exception * FinPointFigure ScrollBars now adjust with zoom in/out * FinPointFigure draws its parent/mounting half-body (w/front & back terminators) ScaleSelector Text updates with +/- buttons * FinPointFigure now auto-scales correctly * excised EXTRA_SCALE (=S) factor in ScaleFigure Code harmonizes the border pixels variables in the scalefigure package removed interface that was only inherited by the single AbstractBaseClass * Reduce redundant methods in Scalefigures, and harmonize common function names FlightConfiguration now exposes the BoundingBox method for its rocket * updated BoundingBox class to be more useful * Refactored naming in ScaleSelector to be more consistent 'Zoom' -> 'Scale' Resolved some sources of phantom whitespace Spacing on component configuration * fixed warnings and made variable names more explicit in FinSetConfig Dialogs
