Goals were good fuel consumption and thrust-to-weight ratio, and very low production cost. The resulting FJX-2 turbofan engine showed the potential to meet all of these goals. The development of the engine was carried through to proof of concept testing of a complete engine system. The proof of concept engine was ground tested at sea level and in altitude test chambers. A turboprop derivative was also sea-level tested.", "item_img_path" : "https://covers2.booksamillion.com/covers/bam/1/28/723/020/1287230202_b.jpg", "price_data" : { "retail_price" : "17.75", "online_price" : "17.75", "our_price" : "17.75", "club_price" : "17.75", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
