Propeller development programs

One example is an in-house R&D benchmark, not a customer project: Tulkas modeled the geometry of a commercially available APC 13x8 propeller as an internal reference point and developed a carbon fiber 13x8 propeller with a more efficient blade profile. In in-house static thrust test conditions, the redesigned propeller showed an approximate 6% efficiency gain over the reference geometry. This was a comparative in-house engineering study, not a supply or collaboration relationship with the reference brand, and the figure is specific to that one benchmark rather than a general performance claim.

In anonymized form: for a fan-manufacturing customer, Tulkas developed a composite fan blade production process and has since remained that customer's production partner for the part. The customer name and part-specific figures are withheld; the pattern shown is a prototype-to-serial-production process handed off as a controlled, repeatable manufacturing method rather than a one-off delivery.

Customer and project names are only published with explicit written approval or from a verifiable public source. Where that approval doesn't exist, we describe the engineering pattern instead of the client.
