    9. Insect flight muscles

    Most insect species have wings as adults and are able to fly. Unlike birds and bats, insect wings are not modified fore limbs, but are extensions of the cuticle of the meso- and meta-thoracic segments. These two thoracic segments also have prominent muscles used for generating the wingbeat Flight muscles of bats and birds attach directly to the wings, and pull the wings up and down. In insects, only dragonflies and damselflies have muscles attached directly to the wing and these muscles only produce the downstroke for the wingbeat. In all other flying insects, both the downstroke and upstroke of the wingbeat are produced in response to contractions by muscles…

    Hollow Bird Bones – Adaptations for Flight

    Bird flight is beautiful, right? Like, wouldn’t it be amazing if humans could fly? The answer is unfortunately, no. Because birds have so many compromises built into their bodies to enable them to fly up in the sky. Things that make them lighter, stronger, or more rigid. Let’s take a tour through bird bones and I’ll show you what I mean. Many bird bones are thin and delicate, which helps save weight. And many of their bones are hollow. Hollow bones should technically be lighter to allow the bird to lift themselves into the air (more on that in a minute). But you know what mammals do on the inside…

    Flight of the Luck Dragon – Kinetic LEGO Model

    Hey everyone, Jason here. Earlier this year I posted some modifications to the dragon dance set to smooth out the motion and since then I have been experimenting with the mechanism a little bit more, but instead of continuing to modify that set I thought I would just build my own dragon, and if you’re a fan of The Neverending Story, you might recognize Falkor, the Luck Dragon from that movie. I’ve also included some imagery from the movie into the model, including the ivory tower, the Southern Oracle and the black section on the stand represents the Nothing, which is the evil force that is overtaking the world, and…

    Perpetual flight: The incredible technology behind non-stop drones | Fatema Hamdani

    So when we look at UAV platforms (or drones as we call them commonly) there are multiple different types of platforms. There’s rotary devices or multi-rotor. And then there’s fixed-wing UAV platforms. Fixed-wing cover the larger use cases where you’re talking about flying them anywhere from 2,000, 16,000 going up to 35,000 feet, which is the regular airspace under which aircrafts operate as well. And fixed-wing UAVs are categorized by their size and weight starting from Group 1 which is the smallest going up to Group 5, which are the larger ones which carry way larger payloads and might also be used for offensive purposes that might carry missiles and…

    UB’s ‘flight simulator’ for teachers

    [ UB’s flight simulator for teachers ] [ Rebekah Lamb, Enterprise Charter School ] Normally, the classroom teacher will take control of the classroom and won’t give it fully to the student teacher, so this helps it so that the student teacher has the full role of classroom management without the classroom teacher interfering. [ Richard Lamb, Associate Professor, UB Graduate School of Education ] Working here today at Enterprise really helped us understand the challenges that the teachers face every day in the classroom and gives us the opportunity to make use of the creative and innovative ways that they work with the children here at Enterprise.
