The NFL Helmet Challenge Symposium

Q. What is the NFL Helmet Challenge Symposium?
A. The NFL Helmet Challenge Symposium is an in-person meeting to facilitate collaborations and for experts to provide and share information on, among other topics, the current state of the science around helmets and concussion in the NFL, the NFL Helmet Challenge and the helmet design tools and resources available.

Q. What is the NFL Helmet Challenge?
A. The NFL Helmet Challenge is an innovation challenge that aims to stimulate the development by experts, innovators and helmet manufacturers of a new helmet for NFL players that outperforms, based on laboratory testing, all helmets currently worn by NFL players. Helmet prototypes will be submitted for testing in laboratory conditions that represent potentially concussive impacts in the NFL. The challenge will culminate in May 2021 with applicants’ submissions of helmet prototypes, which will be evaluated by scientific and medical experts to compete for up to a $1 million award. This challenge is the next phase in the NFL’s Engineering Roadmap, which aims to improve the understanding of football biomechanics and to create incentives for small businesses, entrepreneurs, innovators and helmet manufacturers to develop new protective equipment.

The NFL Helmet Challenge

Q. What criteria will be used to assess my helmet design?
A. Helmets must meet certain design constraints based upon laboratory test performance and comparability to the physical attributes of helmets currently used by NFL players. Helmet prototypes must achieve a Helmet Performance Score (HPS) of 0.70 or lower to be eligible to win the NFL Helmet Challenge. HPS is calculated using the test conditions and scoring methods described in the helmet test protocol. The full set of requirements for the design (the “Design Constraints”) are listed below.

The Design Constraints are based on the laboratory test performance and physical attributes of helmets currently used by NFL players. The test conditions used to evaluate laboratory performance of submissions have been specified based upon the type and severity of impacts NFL players experience during NFL games, which may not be applicable to other levels of play outside the NFL.

Helmet prototypes submitted for NFL Helmet Challenge testing must meet the following Design Constraints:

  • Submissions must be a complete helmet system suitable for use in the NFL and able to complete testing under the helmet test protocol.
    • While plastic deformation of the faceguard, and superficial damage (such as scuffing) to the helmet shell/guard are expected during testing under the helmet test protocol, the submission must remain intact and ready for use or continued testing (e.g., it must not sustain cracks to the shell or fracturing or permanent set of any energy-absorbing component during testing). Helmets must be submitted along with seven faceguards with eye and oral protection, seven chinstraps and associated attachment hardware. Helmet-mounted hardware must remain as provided (for example, parts on the straps may be replaced during testing, but not parts on the helmet).
  • Submissions must be capable of satisfying the testing, durability, and other requirements set forth by NOCSAE standards ND001, ND002, ND081, and ND087.
  • Novel designs (for example, “diving bell” type designs that structurally engage the head with the torso and thereby create the potential for greater effective mass when striking another player) must be shown to not create new safety risk for participants or limit range of motion.
  • Submissions must allow range of motion and range of vision comparable to helmets currently in use in the NFL.
  • Mass, dimensions, and standoff of submissions must be comparable to helmets currently used by NFL players:
    • Total helmet mass, including faceguard and retention system (i.e. chin strap or equivalent) shall not exceed 2.2 kg.
    • Helmet width measured without the faceguard when the helmet is positioned on the Hybrid III headform shall not exceed 255 mm, and maximum width with the faceguard shall not exceed 268 mm.
    • Helmet length projected onto the Hybrid III x-y plane shall not exceed 308 mm from the most anterior point of the helmet to the most horizontal posterior point on the helmet when donned on the Hybrid III headform.
    • Faceguard standoff shall not exceed 70 mm.
    • Top standoff must be less than or equal to 82 mm.
    • When donned on the Hybrid III 50th percentile male headform, the helmet must generate less than 77 kPa of pressure against the dummy skin at any location of contact as measured according to the methods in the helmet test protocol.

A panel of expert judges including helmet experts, biomechanical engineers, medical experts and materials experts will determine whether a helmet submitted for NFL Helmet Challenge testing meets these Design Constraints in order to be eligible for testing under the helmet test protocol identified above. Any submission is subject to disqualification if the expert panel determines that the design introduces or has the potential to introduce a new risk or consequence that is not addressed by the helmet test protocol and to which the application has not provided adequate supporting information. All participants in the challenge must agree to and comply with the NFL Helmet Challenge Rules and Regulations.

Q. How will the Challenge winners be determined?
A. Helmet prototypes that meet the Design Constraints must achieve a Helmet Performance Score (HPS) of 0.70 or lower to be eligible to win the NFL Helmet Challenge.

In the case of multiple submissions meeting the Design Constraints above, the panel of expert judges will score submissions based on an evaluation of a set of Assessment Criteria, including:

  • The HPS score.
  • Is the submission feasible for use in the NFL?
  • Does the submission have high potential for acceptance by NFL players (design, appearance, perceived comfort, inertia, hearing, venting, donning/doffing, etc.)?
  • Does the submission have the ability to perform in the NFL environment? For example, would it tolerate storage (at a low range of 10° F with upper range of 120° F), repeated cleaning, exposure to sunlight, prolonged heating, sweat and potentially corrosive environments?
  • Does the submission have the ability to attain certification under the NOCSAE standards?

Q. What is the award for winning the NFL Helmet Challenge?
A. Submissions that satisfy all of the Design Constraints will be eligible to win a prize of up to one million dollars ($1,000,000). In the event that multiple submissions satisfy all of the Design Constraints, up to three submissions may be awarded a portion of the one million dollar ($1,000,000) prize. One Grand Prize winner will receive at least five hundred thousand dollars ($500,000). Submissions will be ranked according to their total score, and the prize will be apportioned based on those scores and the Assessment Criteria; however, the Judging Panel reserve the right to award fewer than the anticipated number of cash awards (including zero awards), in the event an insufficient number of eligible Applications meet the Judging Criteria for the challenge, in the Judging Panel’s sole discretion.

Q. Who will do the testing of the physical prototype?
A. Physical prototypes will be tested by Biocore LLC and evaluated by an expert panel, including a number of engineers, scientists, researchers and other experts.

Q. What is HPS?
A. HPS is based on the kinematics of the Hybrid III head in a series of 18 impacts using a linear impactor striking the helmeted head at 3 speeds at each of 6 locations on the helmet. An intermediate set of metrics (viz. HIC, DAMAGE, and HARM) are required for the calculation of HPS, as detailed in the helmet test protocol.

Q. How were the impact conditions determined?
A. The impact conditions used in the calculation of the HPS are based on analysis and reconstructions of certain on-field impacts previously associated with concussions in the NFL. The impact conditions are specific to the NFL and may not apply to other levels of play.

Q. Are finite element models of modern helmets available?
A. Biocore and Football Research Inc. (FRI), with funding support provided by the NFL, have collaborated with partners at the University of Virginia, Wake Forest, KTH Royal Institute of Technology and the University of Waterloo to develop open-source finite element (FE) models of four modern football helmets and associated impact test methods and equipment, including the Hybrid III headform and neck. These models are available subject to the licensing terms . Technical specifications and experimental validation data for the models were developed by Biocore and provided to these university partners, who created the computational models using physical helmets. The models are available here.

Q. Where can I download the Hybrid III headform finite element model?
