  Whisper Aero proposes investigating a novel electric propulsor designed to achieve ultra low noise, high specific power, and high efficiency both at static and high speed cruise conditions. These capabilities are critical to enable eVTOL aircraft to achieve scaled market use in urban areas, and the wide breadth of mission applications across commercial, public use and military aircraft. The eQ ...

  Whisper Aero proposes building a flexible acoustic framework designed to be user-friendly, that enables engineers to easily connect multi-fidelity aerodynamic tools to multiple acoustic models. Though noise is a significant constraint in military and consumer missions, OEMs are still struggling to design for acoustics due to difficulties connecting multi-fidelity, multiple paradigm aerodynamics ...

Polyimide (PI) is an important engineering polymer with excellent thermomechanical, electrical and chemical resistant properties at high temperatures. However, melt processing of polyimide is difficult. At present, it is limited to filmic structure or compression molding. This proposal posits two concepts to improve melt processibility of PI. From prior research, we demonstrated 1) imidi ...

Sagetech Avionics, working with the University of North Dakota ( UND) Aerospace Foundation, intends to develop and produce a very low size, weight and power (SWaP) detect and avoid (DAA) solution suitable for use in Group 2 or larger UAS, UAM aircraft, with civil and military applicability. The envisioned solution contains integrated transponder and ACAS-Xu functionality for cooperative target tra ...

A novel microstructural phenomenon in 3D printed polymer composites has been discovered, which yield unusually high strength and stiffness. This results in excellent properties not only in the primary print direction, but also transversely to the printed beads. This project will further quantify the properties of this process and evaluate the out-of-plane transverse properties. Based on the proper ...

Both the nascent Air Mobility industry and the DoD are concerned with noise emissions/perception resulting from the VTOL operations over cities or flying undetected over hostile territory. For AFSOC, flying a VTOL silently is paramount. Most ORBs propulsion systems employ a rotary wing, multiple propellers,  or ducted fans. Jetoptera pioneered the Fluidic Propulsive System (FPS) to generate and a ...

Demonstrating variable cost-to-manufacturer reduction of composites intensive flight vehicles for commercial market applications demands a significant departure from established/legacy thought processes, material selections and manufacturing technologies.

Our proposal describes a Phase I commercialization research plan to provide linear, non-crosslinked polymers via a patented metal-free ring-opening metathesis polymerization (MF-ROMP) technology. Our track record with the MF-ROMP method and preliminary results relevant to the US Army needs indicate that we are uniquely suited to provide linear polymer and copolymers, incorporate polar functional g ...

We are proposing a method to estimate 3D road surface dimensions by applying photogrammetric reconstruction techniques to images of a simulated road surface acquired using two, color line scan cameras.  Estimated 3D dimensions of road surfaces will be compared to laser profilometer measurements to confirm their accuracy and resolution. Data analytics will provide dimensional data sufficient for d ...
