Welcome to the NASRA (Norfolk and Suffolk Rocketry Assocation) Hellesdon Flight Physics Lab official website.

The Hellesdon Flight Physics Lab (HFPL) are involved in the following:

• Building custom data models for use by NASRA members.
• Writing application software to assist our members design rockets.
• We are involved jointly with the DJPL in the Flight Data Systems Division which involves the collection and analysis of flight data.
• Reviewing and improving our models based on the actual data we collect in the field.
• Assist in the design and build of all NASRA experimental rockets.

Below is a list of applications we currently provide on the web (we will add more when time permits):

• Parachute Size Calculator
• Decent Velocity Calculator
• Rocket Simulator
