Preliminary design project for a gear pump intended for the F100-PW-229 turbofan engine's afterburner fuel system. **Engine and Pump Parameters** *The pump is designed for the F100-PW-229 turbofan engine, which has a maximum thrust of 12,940 daN with afterburner *The project assumes a fuel density of 800 kg/m³ and a pump rotational speed of 3200 rpm. * The calculated fuel mass flow rate is 7.37 kg/s, and the required pressure increase is 12 MPa *The required power to drive the pump is calculated to be 122,810 W * [cite_start]The design assumes a mechanical efficiency of 0.9 and a volumetric efficiency of 0.85 **Gear Geometry** * The proposed gear dimensions are based on an involute tooth profile * Key dimensions include a tooth module m_0=5 mm, a number of teeth z=10, and a rim width b=30 mm * Other design factors include a reference pressure angle alpha_0=20° and a radial clearance coefficient c*=0.25 **Pump Verification and Schematic** * The suitability of the gear pump was verified using a kinematic speed specificity parameter n_sQ, which was calculated to be 2.994. That proves usecase of gear pump. * The document includes a schematic of the designed gear pump and a parts list
