Campbell F: “Flying Easter Egg”.

This cabin monoplane was designed by the american Hayden S. Campbell in the mid-1930s. Pretty modern twin-boom mid-wing in configuration, it was powered by a 82 hp Ford V-8 automobile-derived pusher engine. The Campbell F’s more interesting feature was its all-magnesium construction, specially its clean monocoque fuselage pod. Only one example seems to have been produced; it met its end during a demonstration flight.

Pretty obvious nickname’s origin.

  1. Wonder if being magnesium let to it being consumed a little more rapidly than otherwise in that end it met.
    I could have Googled to find out but I’m in the mood to talk before searching on my own initiative.

  2. You know, Magnesium is light. Once upon a time, Soviets built air cooled tank engines in magnesium; their enemies soon discovered that by throwing a Molotov coktail in the grill for cooling air, engine burnt, same as magnesium used when flash bulbs did not exist.
    About car engines in airplanes, there’s an interesting article by Don Sherman, Smithsonian Institution: ‘Power Struggle -Why can engines won’t fly’, Air&Space, Dec 1996-Jan 1997. The case of engine for Lancair is described, and illustrative. Blessings +

    • Good reference!. For this type of application, perhaps the John Deere SCRAE 2034R Wankel engine, over 400 HP, SAE paper 890324, could make a good choice. I don’t know about reasons for discontinuation of work in this promising Rotary Engine. Blessings +

        Big-block Chevy engines return to the skies
        A Texas group in the Midland/ Odessa area is revving up plans to build the Orenda 600, an aircraft engine based on an eight cylinder big-block Chevy racing engine.

        The twin-turbo Orenda 600, first produced in the late 1990s, is going into production again.

        Trace Engines holds all the rights to the engine, which went into production in the late 1990s in Nova Scotia but was discontinue about five years ago.

        Trace expects to spend about $20 million to set up a manufacturing plant for the engine, which was previously certified for flying but has yet to make much impact on the commercial market. Originally, the engine was touted as a low cost replacement for turbine and radial engines in the 600-hp range.

        The new aircraft manufacturer is two years away from starting production. The Orenda weighs in at 750 lb (minus cooling system) and with its twin turbochargers is said to use less fuel at cruising altitude than comparable Jet A-powered engines.

        The Texas plant should be in full production in three years.
