@Gui-FernandesBR | @phmbressan could you please confirm if I need to evaluate static margin for each rocketpy_rocket.aerodynamic_surfaces.add or can I evaluate it only after adding everything (outside the loop) ?

Line range hint 1-53: Implement multiple fins as per PR objectives.

While the change to the airfoil attribute is an improvement, the PR objectives and linked issue #32 specifically request the implementation of multiple fins instead of a single set. This has not been addressed in the current changes.

To fully meet the PR objectives, consider the following suggestions:

  1. Modify the Fins class to represent a single fin set.
  2. Create a new class, e.g., RocketFins, that contains a list of Fins objects.
  3. Update any relevant methods or functions that work with fins to handle multiple fin sets.

Here's a proposed structure:

class FinSet(BaseModel):
    fins_kind: FinsKinds
    name: str
    n: int
    root_chord: float
    tip_chord: Optional[float]
    span: float
    position: float
    cant_angle: float
    radius: float
    airfoil: List[Tuple[float, float]]

class RocketFins(BaseModel):
    fin_sets: List[FinSet]

This structure would allow for multiple sets of fins to be attached to a rocket, meeting the requirements outlined in the PR objectives and issue #32.

Would you like assistance in implementing this structure or creating a new issue to track this task?

2-2: LGTM: Import statement updated correctly.

The addition of List and Tuple to the import statement from typing is necessary to support the new type annotation for the airfoil attribute in the Fins class.


37-37: Airfoil representation improved, but multiple fins not addressed.

The change from airfoil: str to airfoil: List[Tuple[float, float]] allows for a more detailed representation of airfoil data, which is a positive improvement. This change enables the storage of multiple coordinate pairs to define the airfoil shape more precisely.

However, this change does not directly address the PR objective of implementing multiple fins instead of a single set. The Fins class still represents a single set of fins, not multiple sets as mentioned in the linked issue #32.

To verify if multiple fins are implemented elsewhere, let's search for any changes related to fins in other files:

lib/models/rocket.py (1)

63-80: LGTM! The fins attribute change successfully implements multiple rocket fins.

The modification from Optional[Fins] to Optional[List[Fins]] aligns with the PR objective of allowing multiple sets of fins. This change enhances the flexibility of rocket design while maintaining backwards compatibility.

Consider updating the default airfoil value to a more realistic shape. The current [(0.0, 0.0), (0.1, 0.1), (0.2, 0.2)] appears to be a placeholder.

Please ensure that all existing code using the fins attribute and the airfoil parameter has been updated to accommodate these changes. Run the following script to identify potential areas that may need attention:

140-151: ⚠️ Potential issue

Ensure Compatibility with Python Versions Below 3.10

The use of the match statement requires Python 3.10 or newer. If your project needs to support earlier Python versions, consider replacing the match statement with an if-elif-else construct.

Apply this diff to replace the match statement:

-        match kind:
-            case "TRAPEZOIDAL":
+        if kind == "TRAPEZOIDAL":
             rocketpy_finset = RocketPyTrapezoidalFins(
                 n=fins.n,
                 name=fins.name,
                 root_chord=fins.root_chord,
                 tip_chord=fins.tip_chord,
                 span=fins.span,
                 cant_angle=fins.cant_angle,
                 rocket_radius=fins.radius,
                 airfoil=fins.airfoil,
             )
-            case "ELLIPTICAL":
+        elif kind == "ELLIPTICAL":
             rocketpy_finset = RocketPyEllipticalFins(
                 n=fins.n,
                 name=fins.name,
                 root_chord=fins.root_chord,
                 span=fins.span,
                 cant_angle=fins.cant_angle,
                 rocket_radius=fins.radius,
                 airfoil=fins.airfoil,
             )
-            case _:
+        else:
             raise ValueError(f"Invalid fins kind: {kind}")

66-71: Approve changes with optimization suggestion.

The implementation of multiple fin sets aligns well with the PR objectives. However, consider optimizing the static margin evaluation.

Consider moving the evaluate_static_margin() call outside the loop to improve performance:

 rocketpy_finset_list = cls.get_rocketpy_finset_list_from_fins_list(
     rocket.fins
 )
 for finset in rocketpy_finset_list:
     rocketpy_rocket.aerodynamic_surfaces.add(finset, finset.position)
-    rocketpy_rocket.evaluate_static_margin()
+rocketpy_rocket.evaluate_static_margin()

This change would evaluate the static margin once after all fin sets have been added, potentially improving performance.

lib/models/rocket.py (1)

63-80: Consider adding unit tests for multiple fins support

With the introduction of support for multiple fins, it's important to ensure that this functionality works as expected. Consider adding unit tests to cover scenarios with multiple fins configurations.

Would you like assistance in creating unit tests for this new functionality?

1-1: LGTM: Import changes are appropriate.

The addition of List from typing is necessary for the new method's type hinting. The Self import, while not visible in the changes, may be used elsewhere in the file.


140-150: LGTM: Well-implemented method for processing multiple fin sets.

The new get_rocketpy_finset_list_from_fins_list method is well-implemented:

  • It correctly converts Fins objects to RocketPyFins objects.
  • Proper type hinting is used for input and output.
  • The method handles the case of an empty fins list.
  • The implementation is concise and clear.

This addition effectively supports the new multiple fins feature.

74-78: ⚠️ Potential issue

Verify handling of updated airfoil parameter

The airfoil parameter in the Fins class has been changed from a string to a List[Tuple[float, float]]. Ensure that all code interacting with Fins.airfoil accommodates the new data structure.

Run the following script to find usages of Fins.airfoil:

#!/bin/bash
# Description: Find all occurrences where Fins.airfoil is accessed or modified.

# Test: Search for code accessing Fins.airfoil. Expect: All usages handle List[Tuple[float, float]].
rg --type py 'Fins\..*airfoil' -A 5 -B 5

63-63: ⚠️ Potential issue

Ensure compatibility with updated fins attribute type

The fins attribute has been changed from Optional[Fins] to Optional[List[Fins]]. Please verify that all references to Rocket.fins in the codebase are updated to handle a list of Fins instances instead of a single instance.

Run the following script to find usages of Rocket.fins:

27-29: LGTM: AngleUnit enum added correctly.

The new AngleUnit enum is a good addition, providing a clear way to specify angle units for airfoil data.

Consider adding a docstring to the AngleUnit class to explain its purpose and usage. For example:

class AngleUnit(str, Enum):
    """
    Enum representing the unit of angles used in airfoil data.
    """
    RADIANS: str = "RADIANS"
    DEGREES: str = "DEGREES"

42-42: LGTM: Fins class updated to support detailed airfoil data.

The modification of the airfoil attribute in the Fins class is a significant improvement. It now supports a more structured representation of airfoil data, including coordinate pairs and the angle unit.

Consider adding a comment or updating the class docstring to explain the new airfoil attribute structure. For example:

class Fins(BaseModel):
    """
    Represents the fins of a rocket.

    ...

    Attributes:
        ...
        airfoil (Tuple[List[Tuple[float, float]], AngleUnit]): 
            A tuple containing a list of coordinate pairs defining the airfoil shape,
            and the unit (RADIANS or DEGREES) used for the angles.
    """
    # ... other attributes ...
    airfoil: Tuple[List[Tuple[float, float]], AngleUnit]

This will help users understand how to properly provide airfoil data.

lib/services/rocket.py (2)

66-71: Implement multiple fin sets and optimize static margin evaluation.

The changes successfully implement the ability to handle multiple fin sets, addressing the main objective of the PR. However, as mentioned in a previous comment, the static margin evaluation can be optimized.

Consider moving the evaluate_static_margin() call outside the loop to improve performance:

 rocketpy_finset_list = cls.get_rocketpy_finset_list_from_fins_list(
     rocket.fins
 )
 for finset in rocketpy_finset_list:
     rocketpy_rocket.aerodynamic_surfaces.add(finset, finset.position)
-    rocketpy_rocket.evaluate_static_margin()
+rocketpy_rocket.evaluate_static_margin()

This change will evaluate the static margin once after all fin sets have been added, potentially improving performance.


140-150: LGTM: New method for handling multiple fin sets.

The new get_rocketpy_finset_list_from_fins_list method correctly implements the conversion from Fins to RocketPyFins objects, addressing the PR's objective. The empty list check is a good defensive programming practice, and the method uses appropriate type hinting.

Consider using a list comprehension for a more concise implementation:

@classmethod
def get_rocketpy_finset_list_from_fins_list(
    cls, fins_list: List[Fins]
) -> List[RocketPyFins]:
    return [cls.get_rocketpy_finset(fins, fins.fins_kind) for fins in fins_list] if fins_list else []

This change maintains the same functionality while making the code more compact.

2-2: LGTM: Import statement updated correctly.

The addition of Tuple and List to the import statement from the typing module is appropriate and consistent with their usage in the updated Fins class.


Line range hint 1-58: Overall changes look good, but additional implementation needed for multiple fins.

The modifications to the Fins class and the addition of the AngleUnit enum improve the capability to define detailed airfoil data. This is a step in the right direction for enhancing rocket design features.

However, the current changes don't directly address the primary objective of implementing multiple fins as mentioned in the linked issue #32. To fully meet the PR objectives, consider the following:

  1. Modify the rocket model (likely in a different file) to accept an array of Fins objects instead of a single Fins object.
  2. Update the POST rocket route to handle multiple fin sets.
  3. Implement logic to evaluate the static margin after adding all aerodynamic surfaces.

To verify the current implementation of fins in the rocket model, we can run the following script:

This will help us understand the current implementation and guide the necessary changes to support multiple fins.

lib/models/rocket.py (1)

63-76: LGTM! Changes align with PR objectives, but consider additional steps.

The modification of the fins attribute from Optional[Fins] to Optional[List[Fins]] successfully implements the capability to attach multiple rocket fins, as outlined in the PR objectives. The default value provides backward compatibility, which is a good practice. The airfoil parameter change also addresses the bug fix mentioned in the PR summary.

Consider adding a comment above the fins attribute to explain the new structure and its purpose. For example:

# List of Fins objects allowing multiple fin sets for complex rocket designs
fins: Optional[List[Fins]] = [...]

Ensure that other parts of the codebase that may expect a single Fins instance are updated accordingly. Run the following script to identify potential areas that need attention:

Would you like assistance in updating the documentation and unit tests to reflect these changes? This could include:

  1. Updating API documentation to explain the new multiple fins capability.
  2. Adding or modifying unit tests to cover scenarios with multiple fin sets.
  3. Updating any example code or tutorials that demonstrate rocket configuration.
✅ Verification successful

Verification Successful! No conflicting usages of Rocket.fins found.

The search for Rocket.fins references across all Python files did not reveal any unexpected or conflicting usages. This confirms that the modification from Optional[Fins] to Optional[List[Fins]] is correctly implemented and does not adversely affect other parts of the codebase.
