thrustcurve-db

thrustcurve-db

This module is a rebundling of the model rocket motor data available on John Coker's excellent thrustcurve.org website ("TC") as a stand-alone JSON file. The data is an array of motor items consistent with TC's SearchResponse#results schema.

See also, the included TypeScript definitions.

Alterations

In addition to the SearchResponse data, the following alterations have been made:

• All numbers are rounded to a precision of 4 digits.
• Most (but not all) motors include a samples array containing the thrust data found in the TC /api/vi/download endpoint.
• samples data is normalized to insure the first data point is always [0, 0]

For full details of how this data set is compiled, please refer to the build/build.js script in this repository.

Installation

npm i thrustcurve-db
yarn add thrustcurve-db

Usage

ESM

import MOTORS from 'thrustcurve-db';

CommonJS

const MOTORS = require('thrustcurve-db');

Note: Users running node may need to supply the --experimental-json-modules flag

Fetch from JSDelivr CDN:

const MOTORS = await fetch(
  'https://cdn.jsdelivr.net/npm/thrustcurve-db@latest/thrustcurve-db.json'
).then(res => res.json());

Example

// Find all J motors currently in production
MOTORS.filter(m => m.availability === 'regular' && m.impulseClass === 'J');
