STATEMENT OF WORK

(AKIRA: DGEN Aeropropulsion Research Turbofan (DART)

Maintenance and Training)

1. Objective/Requirements NASA DGEN Aeropropulsion Research Turbofan (DART) is a vital test article located at Glenn Research Center. The basis of the DART is the AKIRA DGEN380 turbofan engine which requires scheduled heavy maintenance and repair to enable continued safe operations.

2. Characteristics, Scope, and Specs AKIRA shall perform the following duties:

(2.1) Provide a New Friction Welded High Pressure Turbine (HPT) [Part# 000086-A04] for the

DGEN380

• Remove existing DGEN380 HPT and replace with new HPT installed in DGEN380.

• Provide analysis and documentation of AKIRA’s friction weld process.

• Provide material certification sheets for new HPT.

o Note: the new HP Turbine will be guaranteed for a period of one year. (Intervention by NASA personnel on the DGEN380 Turbofan without the express written approval of AKIRA would release AKIRA from all liability and would void the aforementioned warranty)

(2.2) Provide following.

• Spares and consumables kit consisting of:

o Four (4) pressure transducers (FADEC: Oil Pressure, Fuel Pressure, Ambient Pressure & P3) o Three (3) temperature sensors (FADEC: Oil Temperature, Fuel Temperature, Ambient Temperature) o Two (2) filters (oil and fuel) o One (1) filter screen (Enclosure 1 scavenge pump)

(2.3) Provide a Fan Casing [Part# M38-230017-A03] replacement with capability to include a 1/rev sensor

• Remove existing DGEN380 Fan Casing and replace with new fan casing installed in DGEN380.

• Fan casing to be made to same material standards as original fan casing.

(2.4) Provide a replacement injector set for the DGEN380 [Part# 001465-A01].

• Injector set to consist of o One (1) combustor chamber o One (1) starting injector o Thirteen (13) main injectors o One (1) Glow Plug

(2.5) Perform DGEN380 Heavy Maintenance

• AKIRA shall perform the heavy maintenance at their test facility in Bayonne, France o AKIRA team shall come on NASA site for 2 days to assist in preparing the DGEN380 for shipping.

o AKIRA team shall come on NASA site for 2 days to assist in the engine reinstallation and adjusting operational settings.

• This shall include:

o Full disassembly of DGEN380 o Removal of NASA P3 sensor and replacement with original sensor type.

o Visual inspection o NDE analysis by 3rd of critical parts w/ documentation o Cleaning o Parts replacement (Consumables, etc.)

o New Friction Welded High Speed Turbine Shaft assembly o Full reassembly DGEN380 o Operational validation & tests on AKIRA test bench to check the engine o Conditioning & return to NASA facilities (including the old HPT)

(2.6) Provide DGEN380 Maintenance Training to NASA personnel.

• Provide the equivalent of one week of training, at their test facility, to 2-3 NASA personnel, on disassembly, reassembly, inspection, cleaning, and maintenance procedures. This may be separated in to two phases:

o 2-3 days during the disassembly phase (disassembly, inspection, cleaning, etc.)

o 2 days during the reassembly phase o separated by at least one month.

3. Progress Payments AKIRA may invoice

(3.1) 25% of total cost upon NASA receipt of analysis and documentation of AKIRA’s friction weld process described in section (2.1) and documented confirmation of HPT manufacturing commitment by 23-June-2023.

(3.2) 25% of total cost upon AKIRA assisting NASA on-site DGEN380 shipping preparation and with receipt of DGEN380 at AKIRA facility by 30-September-2023.

(3.3) 50% of total cost upon receipt of DGEN380 at NASA facility and operational verification by 30- November-2023.

4. Place of Performance NASA Glenn Research Center in Cleveland, Ohio, USA

(2-days prior to DGEN380 shipping and 2-days after return of DGEN380 to GRC) AKIRA facility in Bayonne, France.

(All other work described above)

5. Period of Performance Effort shall be performed 01-May through 30-September-2023.
